I am trying to implement a test for valid (printable, in this case)
characters in RPG. If I were doing this in C, it would be simple:
If (isprint(c)) { do_stuff(c) ; }
Similar things can be done with isgraph().
Nearest I can remember, the prototype for isprint in C is:
int isprint(int c)
Now to define this in RPG, I would have expected to do: (Columns not aligned
properly)
D isprint PR 10I 0 EXTPROC('isprint')
D c 10I 0 Value
I tried with an indicator as output, with a character as input, and various
permutations of similar combinations, and have not landed on an RPG solution
that seems to work like I expect. Do any of you know the correct
translation of these functions for definition within RPG?
