RE: compress PDS |
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 /* |
