RE: Regular Expression multi-match not as expected

Hi Dennis

The stab in the dark looks to be right the way I read Bob's article and the
API documentation.

Consider Bob's statement: "The number of elements in this data structure
array must be greater than or equal to the value in parameter 3."

Also, the API documentation for parameter 3 says: "The nmatch value is the
number of substrings in string that the regexec() function should try to
match with subexpressions in preg."

I reckon you only get one match because you've only asked it for one.

Evan Harris

I have absolutely no experience using the regex stuff, but the syntax
of the call in your code example includes "match(1)" as the 3rd
parameter. This doesn't restrict the number of find instances (1) does
it?

Thanks for the reply. Unfortunately, that's required syntax to satisfy the
RPG compiler. If a data element is DIM'd, then RPG expects all references
to it to be subscripted. Rather almost all. CALLP should be one of the
exceptions IMO, but is not.

I thought everyone knew about Bob Cozzi's great handling of this. Check
here if interested: http://systeminetwork.com/node/26451.
