Consumer or Contributor?

Originally written in March 2018 but never published as I never left....... Now that I have it felt right to post it...

Are you Contributor or Consumer?

I have today finished working for my current company in NZ.  I have dozens of reasons why I chose to leave so I will only put out a few.

• I wanted a new challenge.
• My career was going backwards due to numerous structural changes and then outsourcing.
• Same old approach, same old processes that were as sacrosanct as a religious text with no hope of change.
• I realise that there is so much more (good tech) out there than the bubble we’d been enshrined in and due to our skills rarity.
• Promotions were literally waiting for incumbents in the senior roles to die or retire (Lessened with outsource)
• Desire to chase my own dreams.....while I still can.

Another Issue

Sadly, another issue was that I realised I had become surrounded by more consumers than contributors.  This can be true for many teams and companies and is not unique to the team above. 

In my years back in the business it became obvious that many of the developers were consuming my knowledge (I like sharing), but, at the same time, some were opposed to sharing theirs.  There were a few good eggs though and you know who you are :-)

Which type are you?

There are two types of developers in this world. Those that ‘learn/implement/teach and share’.  And then there are those that learn solely to strengthen their individual position, or in this case (at this firm), their collective position.  Some go as far as making areas of expertise for themselves in a vain attempt to make themselves indispensable, not realising that this selfishness was actually harming the growth of the business and stalled their own career.

I've known of developers with 25+ years’ experience in the tools that had never even posted a blog or a forum answer on 2E or Plex.  Their interest in the tools (and tech) was only deep enough to grow their individual product (business) knowledge.  They’d never given back to the wider community, they had only even dined at the free buffet of knowledge.

I had questions in my mind......

• Who are these people?   
• Why was I wasting my time trying to help change this culture? 
• Perhaps it doesn’t need changing?
• Perhaps the problem is me!

In life we choose our friends and they choose us.  With school and work especially, we are often forced together....

Personal Impact

I had let myself get so despondent about this scenario that I know that even if I went for another job right now, my frustration would be etched across my face and it would do me little good.  I place no blame at the feet of the outsource provider through which I was working via....The damage was already done before that deal was struck.

What Next?

I’m not driven by money, power or job title (so many managers have failed to understand this part of my personality) and suffice to say, I will have many options so I am looking forward to finding my happy place.

Now is the time to take a break, recharge my physical and mental batteries and then look for a future challenge or focus full time on my dreams…..

My biggest takeout is, if you have tried your best to improve the environment around you but see no signs of it improving, walk away.  Some places/teams/processes are just broken, channel the energy somewhere that warrants your investment/time... including you.


Look after yourself and live your dreams.....One life.....

p.s. When I got home and told the trouble and strife (wife) that I have resigned.  She said it's the first time she had seen me smiling for a while...... I reckon I made the right call, just in time.

p.p.s. If you find that you are a non-selfish consumer.  i.e. someone who is absorbing the knowledge at present but don't have a forum to pass on your knowledge, that is fine.  Just remember to not become one of the selfish hoarders when your time comes to share your knowledge...

Significant product investment planned. in 2019.

MAJOR ANNOUNCEMENT

It has been announced today that a 130m (USD) investment is planned for Q3 2019 in the midrange application development tools space.

A source in the development group states that "We recognise the intrinsic value of systems that have been developed using these tools.  These tools were pioneers of the low-code phenomenon we know and take for granted today."

They go on to say that "By leveraging the sound principles of data driven development and combining with modern code generators for full web and mobile delivery stacks, we are hoping to see a second dawn and further adoption of these tools, as well as, allowing our existing customers to manage the impact caused by companies focused on digital disruption."

I for one truly welcome such and announcement and I hope that beyond this April fool it could/may happen.

A little trick with *SET CURSOR

A quick little post to kick off 2019....

A colleague of mine had an issue today where he was trying to stop a user having to page down dozens of pages when inserting data via a DSPFIL/PMTRCD W/W (Work with) suite.

He asked me how he can reload the subfile (show the new data) but position the page at the point he (the user) was at, rather than refreshing and defaulting back to the first page again....


The solution is quite simple and as the title of the blog says.......

You use the *SET CURSOR function and set it to a field on the subfile record you wish to remain in focus.  In our case we chose the *SFLSEL field.

What is a reasonable time to resolve an issue?

Today, I experienced a bug whilst building a wide screen definition in 2E.  The build was okay but when I went to use it (in the 2E device design editor), I was getting some low-level errors.

Upon googling the error, I came across this ticket which gave a few workarounds, one of which I implemented.

The given workarounds were:-

1. Set the screen footer to 25 as per the screen print. 
   
2. Set the subfile page size for consuming functions explicitly.  I am assuming they mean…
   
3. Override the YSFLEND model value to *PLUS and not *TEXT or override it in the consuming function via F7=Function Options
   
   
   
   

All of these appear to be perfectly good reasons to postpone fixing this issue up within the product as I am guessing...

• many use the + for subfile,  
• many also forget to move the command line down to row 26 anyhow when creating and generating wide screens (they leave it at 23) and then wonder why they have a 3 row gap at the bottom of their screens 😊

Is it okay though, that 15 years after it was raised, it is still an issue…..?

Multi-Line Edit Oddities

Hiya,

Today I helped a colleague (a very talented one at that) with a small issue around a PMTRCD and usage of multi-line edit for oversized fields.  Something he hadn't seen before.

He was confused as to why his data entry field was showing on the device design and not showing when executed.

Figure 1 shows a mock up of his device design looking pretty standard.

Figure 2 shows the same screen at run-time.  Note the cursor has positioned to the field acting strangely but the underline is not showing.

If you want to recreate this issue I created a file as follows (See Figure 3 and 4) :-

 

Additionally, in the device design we set the long field to multi-line Y and set it to 4 rows and 50 wide.

To resolve the issue was a case of applying a (clearly little known) trick of moving the multi-line field over by one byte.  (Figure 5) 

 

This then allows the run-time screen to paint properly. (Figure 6)

My assumption is that the screen attributes are being corrupted by the multi-line although comparing the source for the DDS didn't highlight anything untoward so I am guessing it is a 5250 issue.  (I also recommend aligning the rest of the fields on the screen.)

Any takers on providing the technical explanation? as a compare source doens't seem to highlight a clear and present danger. (Figure 7)

I've always nudged these over by an extra byte for years and years but I guess some tips and tricks get lost.

Thanks for reading.

The magic roundabout....

“Computer Associates (CA), where products go to die!”

If you were around in the late 90’s and early noughties, the statement above was industry standard and after a brief rename to the COOL range from Sterling Software prior to the CA acquisition in 2000 the tools known as Synon (now CA 2E) and Obsydian/Plex (now CA Plex) have been maintained and supported by CA.

Correction from above…. CA did in fact (the early years) innovate with the tools quite frequently and with good features and enhancements.  CA were responsible for the introduction of the Web Option, Triggers, RPGILE Generator, numerous SQL’s updates and Web Services for 2E as well as .NET Generator for CA Plex (no small feat), Web Services publication and consumption as well as keeping up with a myriad of technology platform refreshes Plex required. 

All in all, a reasonable job. 

Perhaps a 6 out of 10.

Okay, 5.

The point being that these products didn’t go to CA to die. However, in recent years with development budgets reduced and key personnel leaving the rate of change has stalled significantly.  So much so that nowadays a release highlight are items that would have been reserved for minor features or even bug fixes in years gone by.

Whilst the tools haven’t died they are clearly in maintenance mode.  CA moved this group of products to sustaining engineering.  This has a negative context whilst a product is in decline and I feel that other low-code options with better target platforms coverage have emerged into a space once dominated by case and code generation tooling.

Last week Broadcom announced a cash buyout of CA Technologies for over 18b dollars.

Broadcom doesn’t do software…they are a semiconductor business so what does CA provide them:-

1. They may be diversifying their offerings and product range.  Perhaps there are some key products in the CA range that assist in their growth or CA has strong alliances with certain business verticals or a client base the parent organisation may wish to gain access to.
2. Or this is purely a financial decision.  They may have too much cash to burn and need to spend it quickly.  They buy a solid company with a long and attractive maintenance trailing revenue stream and secure long term (almost guaranteed) recurring revenue.  Most likely this means they won’t need to pay any corporation tax for the next year or two as they assimilate this monster of a business.

Perhaps a mix of both but my money is on the second option and that this is merely a financially driven strategic purchase.  

There certainly isn’t any institutional importance for the CA development tools business i.e. CA 2E, CA Plex and CA Gen.  Although these areas are likely to show very high ROI i.e. cost vs revenue on the reporting charts I very much doubt they’ll get anymore focus than they there are currently getting.

Now it would appear, that the final resting place for these (once wonderful and genius) tools is going to be Broadcom.  The new statement being “Broadcom, a place where CA Technologies development tools go to die!”

STOP THE PRESS!!!!!!!

Hopefully not, I hope that the residual value and with opportunities in a safe pair of hands i.e. a company with a low code focus. It is possible to recapture the essence of CASE and reinvigorate these tools.

Probability?: < 10% if Broadcom don’t want to relinquish these tools.

Lee’s take out!

Sadly, it’s probably time to work out what the next big thing is… These tools are now compliance/maintenance focused (at best) and will be stabilised (cease to be supported) as soon as the revenue trail drops below x, whatever x is.  

x for CA or Broadcom is far higher than x for a passionate low-code only vendor.  I beg Broadcom to review the business units at CA and seek a buyer (at a fair price) so this technology has a chance to thrive once more.  These tools practically invented low-code.  In my eyes they are 20 years ahead of the rest.

Thanks for reading.

p.s. I wonder what theynew name will be....Broadcom Plex doesn't have that good a ring to it.....

You have 'Function Options' you know....

PODA PODA PODA PODA PODA PODA

One of the first things that are discussed when you did (if you did) the Action Diagramming course for 2E is PODA.

PODA is an approach to effective function design.

• P is for parameters and the interface.
• O is for options (Function Options)
• D is for device design (Screen/Print)
• A is for action diagram.

The concept being that these all influence the function and getting them correct will mean you’ll write less code and won’t be wrestling with the template (prototypes/patterns).

Bare this in mind for the rest of the blog post.

I was at work the other day and was maintaining some code where once again I could be heard saying, “Whoever wrote this should be shot!".  It’s my preferred (go to) phrase when I see badly written/designed/architect-ed code.

Anyhow in this instance the code was quite simple and generic so I can share it here.

The reason for my comment above was why is this code inside a subroutine called Subroutine?  The actual function ‘Perform Substitution’ was itself and EIF (Execute Internal Function).

I thought to myself, it is okay someone probably wanted to be able to *QUIT from one of the case blocks below…..  NO!!!

Hmmmm.......Perhaps someone was being a dunce!

Anyhow, depending on you model default and EIF can be generated as either inline code or as a subroutine.  I am thinking that this code might be quite old or that someone simply doesn’t understand how the code is generated in 2E. (Probably the later).

Most of you know that you can share subroutines and reduce code bloat using the ‘Share subroutine’ option.  And EIF also has an additional option called ‘Generate as subroutine’.

In the instance above we could have achieved the same result with omitting the sequence block and simply setting the value.

Let’s explore the generated code for a much simpler example.  I have an EEF (Execute External Function) calling and EIF.  The EEF is setting the local context for LCL.*JOB DATE to JOB.*Job Date and then calls the EIF which in turn set the WRK.*Job Date to JOB.*Job Date.

With ‘Generate as subroutine’ set to No we get inline code. (See below).

Taking the original example (see top), if I put the internal code inside a Sequence block I’d get a subroutine. 

See code mock up below.

So although this code looks a little neater, it still isn’t perfect.

Setting the option Generate as subroutine’ to Yes generates slightly difference code.

Overall, in this instance it didn’t matter too much as there were NO *QUIT’s to worry about and the routines weren’t (or couldn’t) be shared etc.  But it does highlight that following PODA can make your programmer life easier, not to mention mine..... as I mop up after you....
