The SYSIN data set is the main input into Assembler H and VS COBOL
II. It contains the ISPF libraries or other partitioned or sequential
data sets that you enter on the Foreground Assembler H and VS COBOL
II Compile panels. This data set is used to find the member that contains
the program to be assembled or compiled. For a PDS, the ALLOC command
would be:
ALLOC FI(SYSIN) DA('proj.lib.type(mem)')
For a sequential data set, the ALLOC command would be:
ALLOC FI(SYSIN) DA('proj.lib.type')
In both commands, lib is the library in which
the member or data set was found.
