Specifying source libraries (SYSLIB)
Use SYSLIB DD statements if your program
contains COPY or BASIS statements.
These DD statements define the libraries (partitioned
data sets) that contain the data requested by COPY statements
in the source code or by BASIS statements in the
input stream.
About this task
//SYSLIB DD DSNAME=copylibname,DISP=SHR
Concatenate multiple DD statements
if you have multiple copy or basis libraries:
//SYSLIB DD DSNAME=PROJECT.USERLIB,DISP=SHR
// DD DSNAME=SYSTEM.COPYX,DISP=SHR
Libraries are on direct-access storage devices. They cannot be in the z/OS® UNIX file system when you compile with JCL or under TSO.
