CPPLEFPL
This stub is a combination of the CPPL and EFPL stubs. It contains the logic to determine if the REXX program is being invoked as a TSO/E command or as a REXX external routine. Once this has been determined, the compiled REXX program is given control with the appropriate parameters.
CPPLEFPL is recommended for most compiled REXX programs running under TSO/ISPF.
