Introducing NetMaster REXX › REXX Process Control

REXX Process Control

You can use the RXCTL command to control currently executing REXX processes.

This command has the following format:

[ RXCTL ] { HE | HI | HT | RT | TE | TS }  
          [ ALL | ID=id ]

Note: The six operands, HE, HI, HT, RT, TE, and TS are also defined as commands. You can use the RXCTL HT or the HT commands; they are the same command.

These operands are analogous to the TSO/E REXX immediate commands. They cause an immediate change to the status of a REXX process.

HE

Halts Execution. This operand halts execution of a REXX process.

HI

Halts Interpretation. This operand halts interpretation of a REXX process.

HT

Halts Typing. This operand halts typing and causes all output (SAY and TRACE) to be discarded.

RT

Resumes Typing. This operand resumes typing and causes all output (SAY and TRACE) to be resumed.

Note: TE and TS are recognized but not supported.

If the current execution environment has only one active REXX process, a command issued without an optional operand affects that process as requested. If there is more than one process, a message is issued.

If the ALL operand is specified, the RXCTL command affects all REXX processes executing in the current environment.

If the ID=n operand is specified, the specified REXX process is affected.
