After a PDS has been subjected to a high volume of activity such as replacing members, adding new member and deleting members there may be unusable gaps or spaces between members stored within the PDS. A compress function using IEBCOPY is provided to compress the members and consolidate all the gaps or spaces into a single area within the PDS.

Ex: Command :
//COMPRESS DD DISP=SHR,DSN=MFI01.SIMOPROD.JCLPROC1
//SYSIN DD *
COPY INDD=COMPRESS,OUTDD=COMPRESS
