RE: Passing a substring as a parm to a proc

[Joel Fritz <JFritz@xxxxxxxxxxxxxxxx>]

Here's an example that doesn't do much, but it passes a substring to a
procedure and modifies it.  You could liven it up with variables for
substring offset and length.

        *************** Beginning of data
*****************************************************************
0001.00 Ddumstring        pr             5

0002.00 Dstring                          5    value

0005.00 Dlongerstring     s             20    inz('12345678901234567890')

0006.00 C                   eval      %subst(longerstring: 5: 5)  =

0007.00 C                             dumstring(%subst(longerstring: 5: 5))

0041.00 C                   SETON

0045.00 D

0046.00 C                   eval      string = 'newva'

0047.00 C                   return    string

0048.00 Pdumstring        e

Subject: Passing a substring as a parm to a proc


Hi all
Is there any possible way that I can call a procedure passing a substring
as a parameter ? The substring will ALWAYS be a fixed length, however it
may vary along a character field.
Regards
John.
