Rexx - ISPF-variables

[Lars Höglund]

Hi

 

Pros and cons about coding ISPF-commands with “rexx variables” or “ISPF variables”?

 

address "ISPEXEC" "LMDINIT LISTID(LIST) LEVEL(XYZ)”

 

use Rexx-var

address "ISPEXEC" "LMDLIST LISTID("list")….”

 

or use ISPF-var

address "ISPEXEC" "LMDLIST LISTID(&LIST)….”

From an efficiency perspective I would use the Rexx-var.   ISPF will scan the command string looking for an ampersand and then do checking for things such as DBCS, 2 ampersands in a row, etc.  Eventually the variable gets substituted.  Not a big amount of overhead,  but more than if REXX just substituted it to begin with.
