Answering my own question [for the archives] - LE expects a COBOL MAIN entry [subtasked or not] to be invoked via the "EXEC PARM=..." convention.
So, in the Assembler middleman I had to take the original pointer in R1 and save it as the only passing parm in an EXEC_PARMS area, then Attach with R1 pointing to A(EXEC_PARMS). The opposite conversion into the CALL <pgm> USING <parms> format is taking place in the COBOL MAIN stub. Unfortunately, the COBOL stub needs to know the NUMBER of such parameters to be able to issue a respective CALL, so for now I am settling just for one such parm. -Victor- ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
