in REXX there is no provision for passing <global> <tokens> between <external> procedures
for procedures inside the same source member read about the EXPOSE clause
if Your rexx runs under the ISPF environment You might use VPUTs and VGETs
if your organization allows the use of freeware applications You might check
www.btinternet.com/~ashleys/fadh_globalv.htm
or write Your own, not that much complicated  |

This call/return structure worked for me.
| Code: |
/* REXX PROGRAM A*/
V1 = 'A-VALUE1'
V2 = 'A-VALUE2'
V3 = 'A-VALUE3'
CALL "B" V1 V2 V3
PARSE VAR RESULT V1 V2 V3
SAY 'BACK IN PROGRAM A VALUES -' V1 V2 V3
EXIT
/* REXX PROGRAM B */
ARG V1 V2 V3
SAY 'IN PROGRAM B VALUES -' V1 V2 V3
V1 = 'B-VALUE1'
V2 = 'B-VALUE2'
V3 = 'B-VALUE3'
EXIT V1 V2 V3 |
