Here's a question regarding PARSEing in REXX on VM/CMS:
 
In parsing, I know you can use a string pattern in a variable, by putting
it in parentheses.  For example:
 
         slash = '/'
         parse value 'dog/cat' with word1 (slash) word2
 
But I can't find how to use a NUMERIC pattern in a variable.  For
example, I might want to break a string at a specific column determined
by the program.  Simplistic example:
 
         column = 4
         parse value 'dog/cat' with word1 (column) word2
 
will use '4' as a string pattern, rather than as a number pattern.
 
 
So, my question is: is there a way to use a numeric pattern in a variable
when parsing?
 
 
Thanks for any help.
