I have been looking at the LE documentation now for days and still not sure what I need to do to have my Assembler program call C or C++ programs. I need this interface to be very efficient because I will be calling these subroutines maybe more than a 1,000,000 times a day. What I have come up with is to use CEEPIPI to build the environment.
LA R5,PPTBL GET ADDRESS OF PIPI TABLE ST R5,@CEXPTBL CEEXPTBL-ADDR -> PIPI TABLE L R15,PPRTNPTR GET ADDRESS OF CEEPIPI ROUTINE * INVOKE CEEPIPI ROUTINE CALL (15),(INITSUB,@CEXPTBL,@SRVRTNS,RUNTMOPT,TOKEN) I will have three subroutines so I think I need to put each one of these routines in the preinit table. Now I think I need to use CEEPIPI again when I want to call each subroutine. ST R11,PARM L R15,PPRTNPTR GET ADDRESS OF CEEPIPI ROUTINE CALL (15),(CALLSUB,PTBINDEX,TOKEN,PARM, X SUBRETC,SUBRSNC,SUBFBC) INVOKE CEEPIPI ROUTINE Note: Note: The C routines have not been created yet, so I can't try these things out. Questions: 1) Do I have it correct? 2) Do I even need LE? 3) The book talks about XPLINK. I don't quite understand it. Is this something I should explore more? ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
