Hi,
Can anyone explain the need for list and execute form of macros?
How it will be useful for re-entrant coding?
Is it not enough for re-entrant modules to allocate dynamic memory and move the DCB parameters into it before using?

Other data mgmnt macros also modify storage (OPEN, CLOSE, etc) These need to be copied to dynamic memory , too. The LIST forms give you the proper fields with fixed values. Point to that area when you issue the execute form of the macro.
