SAS tip: Back in SAS 9.2 as I recall, SAS INSTITUTE enhanced the use of SET statement coding when you might want to consolidate several like SAS files (consider MICS cycles within a file / time-span). Yes, MICS sites can use the %MFILE macro on a SET but still you must know how many cycles you want to select or use SAS OPTIONS NODSNFERR; and code up to cycle "99" or something similar.
If the objective is to select all available MICS DETAIL BATJOBnn cycles then consider this coding technique:
SET _BATX.BATJOB: ; /* trailing colon char selects all available cycles */
The use of either _BATX. or &BATX.. with the MICSSHRx JCL PROC execution allows MICS to determine where the BATCH INFO AREA files in DETAIL reside -- in case your MICS unit may be "split".
And remember to consider other SAS optimization coding techniques, such as using the WHERE statement instead of IF -- and depending on your needs consider adding the SET statement "dataset option" (KEEP=<varlist>) to reduce the SAS overhead with loading your input file(s) with the DATA STEP.
