Coding made easierProgramA discussion of sectioning and linking is contained in “Source program structures”on page 50.listingsThe assembler produces a listing of your source module, including any generatedstatements, and the object code assembled from the source module. You can controlthe form and content of the listing using assembler listing control instructions,assembler options, and user I/O exits. The listing control instructions are describedin Chapter 5, “Assembler instruction statements,” on page 97, and in “Processingstatements” on page 253. Assembler options and user I/O exits are discussed inthe chapters “Controlling Your Assembly with Options” and “Providing UserExits” in the HLASM Programmer’s Guide.The assembler also prints messages about actual errors and warnings aboutpotential errors in your source module.Multiple source modulesThe assembler can assemble more than one source module in a single input stream,if the BATCH option is specified. For more information about the BATCH option,see the section “BATCH” in the HLASM Programmer’s Guide.An “input stream” may contain one or more “source modules”, and may alsoconsist of one or more data sets if the host operating system supports data set orfile concatenation. A “source module” is a single assembly.10 HLASM: V1R6 Language Ref
