Storage requirements

Virtual storage: High Level Assembler requires a minimum of 610 KB of main storage. 410 KB of storage are required for High Level Assembler load modules. The rest of the storage allocated to the assembler is used for assembler working storage.

Auxiliary storage space: Depending on the assembler options used, auxiliary storage space might be required for the following data sets:
  • System input
  • Macro instruction library—either system or private or both
  • Print output
  • Object module output
  • Associated data output
  • I/O exits
  • External functions

Library space: The space requirements for the High Level Assembler load modules (or phases) and procedures are provided in the HLASM Installation and Customization Guide.

Installation: Please refer to HLASM Installation and Customization Guide for installation requirements.
