Debug message issued by VNCRXM03, the REXX exec exit, upon being called by REXX before starting execution of a pipe stage exec. The purpose of the exit is to create and initialize a common set of REXX variables with values unique to each pipe stage exec to control the stage’s processing. For the SAFE stage, it loads the default safe with the message that triggered a message rule to call the exec that called the pipe command.
