   hi Doug,

   Whenever you want to insert a single-quote (apostrophe) into a string in
   RPG, just double-up the quotes.  It doesn't matter whether this is part
   of an expression, named constant or literal -- it always works the same
   way.

   For example, if I wanted to say Scott's Computer, I'd do this:

   string = 'Scott''s Computer';

   See?  the quote in the string where I want the apostrophe is doubled-up.
    It's not any different in your case!  Let's say you want to put it
   between the A and the B in your CONST string:

   D D@INV   C   CONST('!@#-c-&\}|NOT{?><.`~||(),*$+-
   D             %;:"A''BCDEFGHIJKLMNOPQRSTUVWXYZ.')

   (I've deleted some of the extra spaces from the D-spec to hopefully keep
   it from wrapping in the e-mail client)

   See... it's just '' in between the A and the B -- just like it was when
   I did Scott''s Computer.

   Folks tend to get confused (and sometimes even frustrated) when it comes
   to these double-quotes if they end up at the start or end of the string
   where it's adjacent to the starting quotation mark or the ending
   quotation mark (or both).   Personally, I don't find it confusing... I
   just imagine there being other characters... for example... the
   following is easy enough for me to understand:

   'aaaaaa''hello''bbbbbb'

   This results in the string aaaaaa'hello'bbbbbb -- pretty easy to
   understand, right?  I just doubled up the quotes.   If I want to just
   have 'hello' without the aaaaa and bbbbb, all I have to do is delete the
   aaaaaa and bbbbbb from the string.

   '''hello'''

   See... because there's 3 quotes at the start and end, people get
   confused.  But if you imagine the aaaaa and bbbbb between the outer
   quote and the inner quote, it's easier (for me, anyway) to visualize.

   So, again, in your case, if you wanted the ' to be at the start of the
   string you'd do this:

   D D@INV   C   CONST('''!@#-c-&\}|NOT{?><.`~||(),*$+-
   D             %;:"ABCDEFGHIJKLMNOPQRSTUVWXYZ.')

   And I'd find it easier to visualize as CONST('aaa''!@#-c-&\'  It's easy
   enough to see that the '' takes the place of a single quote.  Then, just
   by deleting the aaa at the start, I end up with CONST('''!@# (etc)

   Same thing at the end:

   D D@INV   C   CONST('!@#-c-&\}|NOT{?><.`~||(),*$+-
   D             %;:"ABCDEFGHIJKLMNOPQRSTUVWXYZ.''')

   It's pretty easy once you think of it that way.
