Inputting additional object modules
You can use the INCLUDE linkage editor control statement to specify additional object modules you want included in the phase.
Code the INCLUDE statements before the EXEC statement that invokes
the linkage editor:
// EXEC ASMA90,SIZE=ASMA90
⋮
/*
INCLUDE ASSMPGM
INCLUDE ASSMPGM1
// EXEC LNKEDT
/&
Object modules specified by the INCLUDE statement are written to SYSLNK as job control encounters the statements.
