High Level Assembler (HLASM) and Toolkit Feature

Technical detail

Hardware Requirements

High Level Assembler, and its generated object programs, can run in any IBM ES/9000, 3090, 308X, 43XX, or 937X processor supported by the operating systems listed below under Software Requirements. However, you can only run a generated object program that uses 370-XA machine instructions on a 370-XA mode processor under an operating system that provides the necessary architecture support for the 370-XA instructions used. Similarly, you can only run a generated object program that uses ESA/370 or ESA/390 machine instructions on an associated processor under an operating system that provides the necessary architecture support for the ESA/370 and ESA/390 instructions used.

Software Requirements

HLASM runs under the operating systems listed below. Unless otherwise stated, the assembler also operates under subsequent versions, releases, and modification levels of these systems:

In addition, HLASM requires one of the following:
