When you invoke SAS, SAS automatically issues a FILEDEF command for the parmcards file, assigning to it the DDname FT15F001. SAS uses the parmcards file for internal processing. Lines that follow a PARMCARDS statement in a PROC step are first written to the parmcards file; then they are read into the procedure. The PARMCARDS statement is used in the BMDP and EXPLODE procedures.
