Macro-only assemblies

The associated data file can also be useful for assemblies that have macro processing only (SYSGENs for example). The printing of the generated assembler source is not printed in the listing, but the information is available in the associated data file. Figure 1 shows part of the listing of an assembler program that only includes a macro instruction. The statements generated by the macro instruction (statements 9 through 11) are not printed on the listing. If this program is assembled with the ADATA option, the records produced in the associated data file are in the sequence shown below.
