sFunName = CwErrorFun()
sFunName (string) The name of the P>G PRO function or
procedure in which the last exception was raised.
This function returns the name of the P>G PRO call in which the error occurred. If the error did not occur inside a P>G PRO call, this function returns the empty string. In this way, it can be used to determine if a trapped error is a result of a P>G PRO error or other REXX error.
See the section on error handling for more details.
/* A procedure that exits the script if the last error was not
raised by P>G PRO. */
