The ISPEXEC and ISREDIT host command environments

The ISPEXEC and ISREDIT host command environments are available only to REXX execs that run in ISPF. Use the environments to invoke ISPF commands and services, and ISPF edit macros.

When you invoke a REXX exec from ISPF, the default initial host command environment is TSO. You can use the ADDRESS instruction to use an ISPF service. For example, to use the ISPF SELECT service, use the following instruction:

ADDRESS ISPEXEC 'SELECT service'

The ISREDIT environment lets you issue ISPF edit macros. To use ISREDIT, you must be in an edit session.

Note that the value that can be set in the REXX special variable RC for the ISPEXEC and ISREDIT environments is a signed 24-bit number in the range -8,388,608 to +8,388,607.
