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.

I think you need REXX v4 to do this. column = 4 parse value 'dog/cat' with word1 =(column) word2 For more information, see Cowlishaw, second edition, page 119. -- Jim Foster - MADIF@ROHVM1.BITNET Rohm and Haas Company Systems Programmer Independence Mall West (215) 592-2446, 592-3377 (FAX) Philadelphia, PA 19105

How about using INTERPRET? As in...
number = 4
interpret "parse value 'dog/cat' with word1 "number" word2"
By the way (BTW?): the =(number) construct did not work on my TSO/E
system with REXX370 3.45!

Hello! I don't fi we are talking about Rexx370 parser. But The following code does what you would like to do (using numeric pattern in parsing)... Here is it: /* */ Trace off begcol = 17 endcol = 21 rxcmd = "Parse value DIAG(8,'CP QUERY CPUID') with" begcol "cpuid" endcol Interpret rxcmd Say "CPU model:" cpuid Exit

You're trying to parse everything *BEFORE* the fourth column into the variable "word1" and everything *AFTER* the fourth column into "word2". Try it this way: parse value 'dog/cat' with 1 word1 4 . 5 word2 This template tells REXX to start start parsing the first variable in column 1, the second variable (".", the dummy variable) in column 4, and the third variable in column 5. You'll end up with "word1" set to "dog" and "word2" set to "cat". The slash will be assigned to the dummy variable and discarded. By the way, to parse on a single character (or a string for that matter) you don't need to fool around with assigning it to a variable and putting it in parentheses if you don't want to. Simply, parse value 'dog/cat' with word1 "/" word2 will work just fine to assign "dog" to "word1" and "cat" to "word2". -- ---------------------------------------------------+--------------------------- Never let anyone know you're good at something | Steven King you dislike.
