need help for execute a rexx load module,but got an error

Postby good123 » Mon Jan 03, 2011 9:02 am

I'm trying to use the batch mode to compile a rexx program, and no error or warning
and use STUB=MVS or STUB=MULTI or STUB=CPPL or STUB=EFPL,and STUB=CPPLEFPL.

then i run the job
//STEP1   EXEC  PGM=IRXJCL,PARM='RXRPSTR'                   
//STEPLIB DD  DSN=TDDX.LOADLIB,DISP=SHR                     
//        DD  DSN=MVQ1.RX.LOADLIB,DISP=SHR                   
//SYSEXEC  DD  DSN=ATUY.USERA.PDS,DISP=SHR                   
//SYSTSPRT DD SYSOUT=*                                       
//SYSPRINT DD SYSOUT=*                                       
//SYSTSIN  DD *                                             
  AFK1.NPUDHE.IN    TAPE7                                   
  CYF1.NUUPDZ.OUT   TAPE8                                   
/*                                                           

I got the error message:
46 +++ IF SYSDSN(SRCPDS) /= "OK"
IRX0043I Error running RXRPSTR, line 46: Routine not found

in rexx program RXRPSTR,use an external functuin SYSDSN, rexx code:

IF SYSDSN(SRCPDS) /= "OK" THEN   
DO                                                                 
  CALL WTO_MSG "UNABLE TO FIND DATASET '"SRCPDS"'. PLEASE CHECK IT."
  EXIT  16                                                         
END


how to do,that vaoid the error,or any recommand?

First of all, the IRXJCL program is the REXX interpreter.

SYSDSN is a TSO/E External Function. Therefore, as the manual clearly states:

You can use the SYSDSN function only in REXX execs that run in the TSO/E address space.


You need to run your REXX exec in a TSO/E address space. To do so normally you'd use the TSO/E Terminal Monitor Program IKJEFT01.

MrSpock,thanks for your reply.

i know it.yes, i have test it under IKJEFT01.It is A TSO/E environment,so SYSDSN can
be executed,but i have a question still,Is there no way to do? sometime we wish to compile
the rexx exec to a load module library,and then control by program verssion control system
,and can be compare(Although the source code can be compare in SYSEXEC library)

"but i have a question still,Is there no way to do? "

Do you want to compile REXX using a version control tool, create its load, and then execute the load using IRXJCL?.. and not using any other means of executing a load module?
Please make your requirement clear. May be the below link can help you.

Your situation is not clear; you are discussing two separate topics.

But it looks like you want to build a load module and execute it. You need to call it like you would a load module. I suggest you use:
//SYSTSIN DD *
 CALL 'my.loadlib(myload'

rather than calling it like a regular rexx program.

my request is simple, that rexx exec compile to be a load module,like cobol or assembler. for exaple:
//STEP1 EXEC PGM=IRXJCL,PARM='RXRPSTR' <---- it is a rexx exec,not load module
//STEPLIB DD DSN=TDDX.LOADLIB,DISP=SHR
// DD DSN=MVQ1.RX.LOADLIB,DISP=SHR
//SYSEXEC DD DSN=ATUY.USERA.PDS,DISP=SHR
//SYSTSPRT DD SYSOUT=*
//SYSPRINT DD SYSOUT=*
//SYSTSIN DD *
AFK1.NPUDHE.IN TAPE7
CYF1.NUUPDZ.OUT TAPE8
/*
Change to this

//STEP1 EXEC PGM=RXRPSTR <-----it is a load module
//STEPLIB DD DSN=TDDX.LOADLIB,DISP=SHR
// DD DSN=MVQ1.RX.LOADLIB,DISP=SHR
//SYSEXEC DD DSN=ATUY.USERA.PDS,DISP=SHR
//SYSTSPRT DD SYSOUT=*
//SYSPRINT DD SYSOUT=*
//SYSTSIN DD *
AFK1.NPUDHE.IN TAPE7
CYF1.NUUPDZ.OUT TAPE8
/*

The SYSDSN function in rexx program , when you compile it, which STUB is corect?
//RX$CMP1 JOB ,,CLASS=A,MSGLEVEL=(1,1),MSGCLASS=X,TIME=1440
//* REXX COMPILE PROCUDURE
//* ----------IMPORTANT ---------------------------------------------
//* PREDEFINED STUBS ARE PROVIDED: @PQ04021
//* YOU HAVE TO CHOICE A KIND OF STUBS:

//* MVS PROGRAM WILL BE INVOKED AS AN MVS PROGRAM
//* CPPL PROGRAM WILL BE INVOKED AS A TSO/E COMMAND
//* CALLCMD PROGRAM WILL BE INVOKED BY THE TSO/E CALL COMMAND
//* EFPL PROGRAM WILL BE INVOKED AS A REXX EXTERNAL ROUTINE
//* CPPLEFPL PROGRAM WILL BE INVOKED AS EITHER A TSO/E COMMAND OR
//* A REXX EXTERNAL ROUTINE
//* MULTI PROGRAM SUPPORTS ALL ABOVE NAMED ENVIRONMENTS
//* EXCEPT LINKMVS AND ATTCHMVS. @PQ04021
//*
//* -----------------------------------------------------------------
//REXXCL PROC STUB=EFPL TYPE OF STUB

// COMPDSN='ACX1.RX.SFANLMD', REXX COMPILER LOAD LIB
// LIBDSN='ACX1.RX.SEAGLMD', REXX LIBRARY LOAD LIB
// LIBXDSN='ACX1.RX.SEAGCMD' REXX LIBRARY EXEC LIB
//*-----------------------------------------------------------------
//*-----------------------------------------------------------------
//* COMPILE REXX PROGRAM.
//*-----------------------------------------------------------------
//*
//REXX EXEC PGM=REXXCOMP,PARM='&OPTIONS'
//*-----------------------------------------------------------------
//* THE REXXCOMP IS A LOAD MODULE ,AND IT USED FOR COMPILE REXX
//* EXEC SOURCE CODE,IT WILL PRODUCE OBJECT CODE FOR NEXT STEP TO
//* PREPARE LINK.
//*
//*-----------------------------------------------------------------
//STEPLIB DD DSN=&COMPDSN,DISP=SHR
//SYSPRINT DD SYSOUT=*
//SYSTERM DD SYSOUT=*
//SYSPUNCH DD DSN=&&OBJECT,DISP=(MOD,PASS),UNIT=SYSDA,
// SPACE=(800,(800,100))
//SYSIN DD DSN=ATUY.USERA.SOURCE(RXRPSTR),DISP=SHR
//*
//*-----------------------------------------------------------------

which STUB type and OPTION,is to fit me ? when i use the SYSDSN in rexx program.

Somewhere on this board, in this section, in the last week, someone, possibly yourself, posted a question regarding the use of SYSDSN in a compiled Rexx. In that topic I am sure there is a reference to the manual you require.
The problem I have is that people can explain things quickly but I can only comprehend slowly.
