Specifying object code data sets: SYSLIN and SYSPUNCH

Define the data set that contains your object output with the SYSLIN and SYSPUNCH DD statements. When the OBJECT option is in effect, the object module is written to SYSLIN. When the DECK option is in effect, the object module is written to SYSPUNCH. When both OBJECT and DECK options are in effect, the object module is written to both SYSLIN and SYSPUNCH.

You can direct the SYSLIN data set to either a card punch or an intermediate storage device capable of sequential access:

//SYSLIN   DD   DSN=dsname,UNIT=SYSALLDA,
//              SPACE=(subparms),DISP=(MOD,PASS)

You can direct the SYSPUNCH data set to either a card punch or an intermediate storage device capable of sequential access:

//SYSPUNCH DD   SYSOUT=B
