REXX External Assembler API › REXX and Assembler Programs

REXX and Assembler Programs

NetMaster REXX, like TSO/E REXX, provides an interface that contains the following features:

• You can write programs that provide new ADDRESS (Subcommand) environments.
• You can write external procedures and functions.
• These programs can access certain REXX facilities.
• You can write programs that can be called via the REXX ADDRESS LINK and ADDRESS ATTACH statements.

The interface is a subset of the interfaces described in the TSO/E REXX Reference:

• The interface is one-way. That is, REXX programs can request external interface services. However, external programs cannot request REXX execution. (For example, IRXEXEC and IRXJCL are not supported).
• The interface can make requests to REXX services that are normally available to external programs. For example, IRXSAY and IRXEXCOM are available.
• Some facilities are not available, or are not fully supported.
