Just a guess...MyWorkVar is NOT defined as a varying field & instead of
actually containing the correct value...the MyWorkVar will still contain
trailing blanks... 


Thanks,

Bob,

Could you please spell it out for us less experienced programmers what
is
wrong with the last section of code that will bring on the "learning
experience".

Tks,

Glenn

Remember, %TRIM() is NOT %trimR().
I know a lot (most?) RPG IV programmers use %trim() because of the "I
know
it
works" mentality. But in the rare case when a variable contains
leading
blanks,
%trim() will return a completely different value than %trimR().

I strongly agree with the person who implemented %trim(), %trimR(),
and
%trimL()
in RPG IV that as a developer, you should use the Built-in function
that
applies
and not generically default back to %trim(). If anything, default to
always
using %trimR() and then use %trim() on an exception basis, were
applicable.

  myVar = '   Bob Cozzi   ';
  len  = %Len(%trim(myVar));
  lenR = %Len(%trimR(myVar));

After the above is performed, LEN equals 9 and LENR equals 12.
So if you code this:
  myVar = '   Bob Cozzi   ';
  len  = %Len(%trim(myVar));
  myWorkVar = %trim(myVar);
  callp  someCorJavaAPI(myWorkVar : len);

You're going to have a learning experience.
