This procedure consists of one job step: assembly. Use the name
ASMAC to call this procedure. The result of running this procedure
is an object module written to SYSPUNCH and an assembler listing.
(See Invoking the assembler on z/OS for more details and
another example.)
In the following example, input is provided in the input stream:
//jobname JOB
//stepname EXEC PROC=ASMAC
//SYSIN DD *
⋮
assembler source statements
⋮
/* (delimiter statement)
The statements of the ASMAC procedure are read from the procedure
library and merged into the input stream.
Figure 1 shows the statements that make
up the ASMAC procedure.

Notes to Figure 1:
- 1
- This statement identifies the macro library data set. The data
set name SYS1.MACLIB is an IBM designation.
- 2
- This statement specifies the assembler work data set. The device
class name used here, SYSALLDA, represents a direct-access unit The
I/O unit assigned to this name is specified by the installation when
the operating system is generated. A unit name such as 3390 or SYSDA
can be substituted for SYSALLDA.
- 3
- This statement defines the standard system output class, SYSOUT=*,
as the destination for the assembler listing.
- 4
- This statement describes the data set that contains the object
module produced by the assembler.
