The END instruction marks the end of a source module. However, you can code several END instructions; conditional assembly processing can determine which of several coded or substituted END instructions is to be processed. Also, specifying the BATCH option allows you to supply more than one source module in a single input stream. When BATCH is specified, the assembler completes assembling a source module when an END statement is encountered. If further statements are found in the input stream, assembly of a new source module is begun. See END instruction for more details, and the section "BATCH" in the HLASM Programmer's Guide for information about the BATCH option.

Conditional Assembly: Conditional assembly processing can determine which of several coded or substituted END instructions is to be processed.
