Compile only (IBMZC)

The IBMZC cataloged procedure, shown in Figure 8, includes only one procedure step, in which the options specified for the compilation are OBJECT and OPTIONS. (IBMZPLI is the symbolic name of the compiler.) In common with the other cataloged procedures that include a compilation procedure step, IBMZC does not include a DD statement for the input data set; you must always supply an appropriate statement with the qualified ddname PLI.SYSIN.

The OBJECT compile-time option causes the compiler to place the object module, in a syntax suitable for input to the linkage editor, in the standard data set defined by the DD statement with the name SYSLIN. This statement defines a temporary data set named &&LOADSET on a sequential device; if you want to retain the object module after the end of your job, you must substitute a permanent name for &&LOADSET (that is, a name that does not start with &&) and specify KEEP in the appropriate DISP parameter for the last procedure step that used the data set. You can do this by providing your own SYSLIN DD statement, as shown below. The data set name and disposition parameters on this statement will override those on the IBMZC procedure SYSLIN DD statement. In this example, the compile step is the only step in the job.

 //PLICOMP EXEC IBMZC
 //PLI.SYSLIN  DD  DSN=MYPROG,DISP=(MOD,KEEP)
 //PLI.SYSIN   DD ...

The term MOD in the DISP parameter in Figure 8 allows the compiler to place more than one object module in the data set, and PASS ensures that the data set is available to a later procedure step providing a corresponding DD statement is included there.

The SYSLIN SPACE parameter allows an initial allocation of 1 cylinder and, if necessary, 15 further allocations of 1 cylinder (a total of 16 cylinders).
