Hi All,

I'm just learning REXX. I tried to run the below REXX to allocate the file "REXX.EXEC" to system file - SYSEXEC.
Code:
                                             
  "EXECUTIL SEARCHDD(YES)"                       
  "ALLOC FILE(SYSEXEC) DATASET(REXX.EXEC,",     
  "'SYS3.EDS.TSO.SYSEXEC')SHR REUSE"             
  IF RC = 0 THEN                                 
     SAY 'ALLOCATION TO SYSEXEC IS COMPLETED.'   
  ELSE                                           
     SAY 'ALLOCATION TO SYSEXEC IS FAILED.'   

I have allocated the file "REXX.EXEC" to SYSEXEC by running the above program in ready prompt.I'm getting as "ALLOCATION TO SYSEXEC IS COMPLETED." but still unable to run the exec command implicitly by just typing the member present in "REXX.EXEC" in Ready prompt or in command prompt.

Could you please let me know what i need to do for running exec implicitly.

What error message do you get?
Do a LISTA ST after you execute your SYSEXEC reallocation and verify that the SYSEXEC allocation is as you expect.

reallocating SYSTEM libraries will cause unpredictable results

the ALTLIB command is the proper way to allocate additional libraries to the LOGICAL" search order

You can never (not true, but those in the know know the exception) run an exec implicitly from an ISPF command prompt, unless you've added it to a command table!
