In addition to the TRACE instruction, (see
TRACE)
there are the following debug aids:
- The interactive debug facility
- The TSO/E REXX immediate commands:
- HE — Halt Execution
- HI — Halt Interpretation
- TS — Trace Start
- TE — Trace End
You can use the immediate commands if a REXX exec is running
in the TSO/E address space and you press the attention interrupt key.
In attention mode, you can enter HE, HI, TS, or TE. You can also
use the TS and TE immediate commands in a REXX exec that runs in any
address space. That is, TS and TE are available from both ADDRESS MVS™ and ADDRESS TSO.
- The TSO/E REXX command EXECUTIL with the following operands:
- HI — Halt Interpretation
- TS — Trace Start
- TE — Trace End
You can
use the EXECUTIL command in an exec that runs in the TSO/E address
space. You can also use EXECUTIL from TSO/E READY mode and ISPF and
in a TSO/E CLIST. You can use EXECUTIL with the HI, TS, or TE operands
in a program written in a high-level programming language using the
TSO service facility. See EXECUTIL for
more information.
- The trace and execution control routine IRXIC. You can invoke
IRXIC from a REXX exec or any program that runs in any address space
to use the following TSO/E REXX immediate commands:
- HI — Halt Interpretation
- TS — Trace Start
- TE — Trace End
- HT — Halt Typing
- RT — Resume Typing
See Trace and execution control routine - IRXIC for more information.
