You can use the RXCTL command to control currently executing REXX processes. To do this, use the following syntax:
[ 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.
Halts Execution. This halts execution of a REXX process.
Halts Interpretation. This halts interpretation of a REXX process.
Halts Typing. This halts typing and causes all output (SAY and TRACE) to be discarded.
Resumes Typing. This resumes typing and causes all output (SAY and TRACE) to be resumed.
Note: TE and TS are recognized but not supported.
If none of the operands listed previously is specified, there must be one active REXX process in the current environment (window, INTCMD environment). That process is affected 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.
