Machine requirements

For assembling High Level Assembler programs

Programs written using High Level Assembler can be assembled, including use of the z/Architecture processor machine instructions, the Extended Architecture mode processor machine instructions, and Enterprise System Architecture mode processor machine instructions, on all System/370 family and its follow-on machines supporting the following operating systems:

Linux for zSeries
Linux for S/390

You might require an operating system-specific macro library to assemble programs that run under that operating system, depending on macro usage.

For running High Level Assembler programs

A generated object program using z/Architecture, Extended Architecture (370-XA), Enterprise Systems Architecture/370 (ESA/370), Enterprise Systems Architecture/390 (ESA/390), Enterprise Systems/9000 (ES/9000) or Vector instructions can be run only on an applicable processor under an operating system that provides the necessary architecture support for the instructions used.

Tape device

High Level Assembler is distributed on 3480 tape cartridge.

An appropriate tape device is required for installation.
