Hi,

My actual problem is, Iam invoking a Rexx exec thru another Rexx.

Rexx1 --> Executes Rexx 2 . In rexx2 iam allocating a lib to sysexec and now it is allocated.

When iam trying to execute again the Rexx1--> executes rexx2 .. here the problem occurs .. it is again trying to allocate one more .. time ...As the lib was already allocated ,it fails to allocate again. I tried Free that dataset before it allocates . but it says it was open unable to unallocate the dataset . Is there any way to handle the open dataset and to by pass this particular allocation when it is trying to allocates for the second time

is there any way to overcome this .. situation

Take a look at ALTLIB (and I wish I had a euro for everytime that this has been mentioned).

Use ALTLIB in the main EXEC only once at the start, and then once at the end to reset the additional allocations.

So much cleaner and easier tha doing "hard" changes to already allocated ISPF dd names.
