what is meant by "C 3 P'=' '*' PREV"

Postby Farhaan4mf » Tue Apr 15, 2014 12:51 pm

I need to modify one existing REXX edit macro.
  "C 3 P'=' '*' PREV"                     

I can understand that its asking to change column 3 value with '*' . But what does it mean by P'=' .
Actually I need to remove this line, because I DO NOT want to change the column3 value with * . But when I am deleting this particular line from my macro, the macro is going to infinite loop.

Moreover, how does the above code is different from below one
"ISREDIT CHANGE   P'=' '*' 3"

Have you read up on Picture Strings in the manual?

As Blcakthorn mentions, read about Picture Strings (which can be found in the Help for the CHANGE command).
Hope this helps,

And FIND command
The problem I have is that people can explain things quickly but I can only comprehend slowly.
