The following environment variables have a special meaning for REXX programs:
RXTRACE If the environment variable RXTRACE is set to ON before executing a REXX program, the REXX program is executed in single-step mode. This is equivalent to including the REXX <TRACE command with the parameter ?R. Any other value for the variable is ignored by the REXX interpreter.
Note: The REXX Report 1994 contains a detailed description about the debug facilities of REXX.
Hint: To prevent the execution of a REXX program in single-step mode, even if the environment variable RXTRACE is set to ON, use the statement:
dummy = trace( 'OFF' )
as the first statement of your program. This is very useful to prevent tracing programs like PMREXX for a REXX program "compiled" with programs like REXXCC.
(see also Catching debug output)
RXQUEUE This environment variable contains the name of the queue that the program RXQUEUE.EXE should use if the queue name is NOT specified when RXQUEUE is launched. The default queue used by RXQUEUE is the default REXX queue SESSION. (see also The RXQUEUE filter)
