The High Level Assembler default library is PRD1; the default sublibrary is BASE. All High Level Assembler installation jobs assume you are using the sublibrary PRD1.BASE. If you decide to install High Level Assembler in a different library and sublibrary, you need to change some names in the installation jobs.

If you plan to install High Level Assembler to an existing PRD1.BASE sublibrary, make sure there is enough free space to accommodate the additional library blocks.

To check the space, list the directory information of the PRD1 library, using the LISTDIR command of the LIBR program. Make sure there are sufficient library blocks in the free space.

You can use the Interactive Interface to install High Level Assembler, or the documented sample batch job.
