Thanks Ken
I like that idea
I want to take this time to thank everyone for putting up with my crybaby, depressing e-mails regarding this subject.
I especially want to thank everyone who replied with answers to my questions/rants.
As always ALL answers were AND will be gratefully accepted.
One special ATTABOY to Tim Bronski.
Without your help - who knows what wallowing self-pity I would have been under.
That person you now see skipping down the road - that's me. Well at least for the next 30 minutes or so.

However, I believe I have found another way - not pretty but it seems
to work Even though my coding of
ConvSecretSharedKey = %trim(HldConvSecretSharedKey) + *allx'00';
Did not compile, I can code the following Nullfield = *allx'00'; Where
Nullfield is defined as
d Nullfield s 1000a
And now my coding is
ConvSecretSharedKey = %trim(HldConvSecretSharedKey) + Nullfield;
And
ConvdataToHash = %trim(HldConvdataToHash) + Nullfield:
IMO the compiler is unnecessarily picky about using those special values in expressions.
The way I would code something like this is:
targetfield = *loval ;
targetfield = %trimr(sourcefield) + targetfield ;
This way the code continues to work even if the size of targetfield is increased.
