I know you can bring in variables by using PARSE ARG at the beginning of REXX.

Code:

/*   REXX  */
PARSE ARG FIELD1 FIELD2 FIELD3 FIELD4 FIELD5
IF FIELD1 = 'XXX' THEN DO NOP
exit


When running a REXX in batch and passing information to a PARSE ARG statement, is there any method of continuation available to pick up all the symbolic values if their contents won't fix on a 72 position JCL statement?

Code:

//REXX    EXEC PGM=IKJEFT01,DYNAMNBR=10     
//SYSTSPRT DD  SYSOUT=*                     
//SYSEXEC  DD  DSN=HLQ.REXX.LIB,DISP=SHR
//SYSPROC  DD  DSN=HLQ.REXX.LIB,DISP=SHR
//SYSPRINT DD  SYSOUT=*                     
//SYSTSIN  DD  *                           
PROFILE NOPREFIX                           
REXXPGM FIELD1VALUE FIELD2VALUE FIELD3VALUE etc.

After several tests, I determined you simply put a - (dash) at the end of the first JCL statement and it does continue.

Stored as TESTALL
Code:

/********************** REXX *************************/   
PARSE ARG FIELD1 FIELD2 FIELD3 FIELD4 FIELD5               
SAY FIELD1                                                 
SAY FIELD2                                                 
SAY FIELD3                                                 
SAY FIELD4                                                 
SAY FIELD5                                                 
EXIT                                                       


Code:

//REXX    EXEC PGM=IKJEFT01,DYNAMNBR=10                       
//SYSTSPRT DD  SYSOUT=*                                       
//SYSEXEC  DD  DSN=HLQ.REXX.LIB,DISP=SHR                   
//SYSPROC  DD  DSN=HLQ.REXX.LIB,DISP=SHR                   
//SYSPRINT DD  SYSOUT=*                                       
//SYSTSIN  DD  *                                               
PROFILE NOPREFIX                                               
TESTALL APPLE_ORCHARD PEAR_ORCHARD KIWI_ORCHARD ORANGE_GROVE -

reading the manuals will prevent everybody from posting misleading suggestions
http://publibz.boulder.ibm.com/cgi-bin/bookmgr_OS390/Shelves/IKJ4BK90

use a + or a - as continuation indicator
a + will drop the spaces between the <parameters> a - will not
