JOB parameter

[psomerscsfb]

This works when entered from the command line:
CHGSPLFA PR025RF 514834/PSOMERS/QPADEV0004 1 PRTSEQ(*NEXT) RESTART(1)

This following CL program fails with the message CPD0078: Value '514834/PSO' for parameter JOB not a valid name:
PGM
DCL VAR(&JOB_NAME) TYPE(*CHAR) LEN(27) +
VALUE('514834/PSOMERS/QPADEV0004')
CHGSPLFA PR025RF &JOB_NAME 1 PRTSEQ(*NEXT) +
RESTART(3)
ENDPGM

What am I missing?

The CL program will be called from an RPG program with the JOB parameter being passed.

Each of the three pieces of the job identifier has to be in its own variable. Instead of one &JOB_NAME variable, use 3 variables for job name, user, and job number.
