Thanks CarloM, this is what I did with your gawk proposal to analyse ${0} and populate the variables V_SEVERITY and V_INFO:

Code:
 V_SEVERITY=`echo ${V_MEM_PARAMETERS} | gawk --re-interval '{ matched=match($0," (.{4}) (.{50})$", myarray); if (matched) { print ( myarray[1]);}}'`
 V_INFO=`echo ${V_MEM_PARAMETERS} | gawk --re-interval '{ matched=match($0," (.{4}) (.{50})$", myarray); if (matched) { print ( myarray[2]);}}'`

and these were my results:
Quote:
======= Case 1: OK =======
Argument String = "UNIV ABORTED JOB GS1 VMSDLCEREF 2011/10/25 11:42 0000201 0000000 UNIV56 X vmsdlceref "
Expects:
V_SEVERITY=""
V_INFO=""
Gets:
V_SEVERITY=""
V_INFO=""
NOTE: There should be 56 spaces after vmsdlceref in the argument string, but the forum software strips them.
Quote:
======= Case 2: NOK =======
Argument String = "UNIV ABORTED JOB GS2 VMSDLCEREF 2011/10/25 11:46 0000202 0000000 UNIV56 X vmsdlceref 3333 "
Expects:
V_SEVERITY="3333"
V_INFO=""
Gets:
V_SEVERITY=""
V_INFO=""
Note: there should be 51 spaces after 3333 in the argument string.

======= Case 3: NOK =======
Argument String = "UNIV ABORTED JOB GS3 VMSDLCEREF 2011/10/25 11:49 0000203 0000000 UNIV56 X vmsdlceref 12345678901234567890123456789012345678901234567890"
Expects:
V_SEVERITY=""
V_INFO="12345678901234567890123456789012345678901234567890"
Gets:
V_SEVERITY=""
V_INFO=""
Quote:
======= Case 4: OK =======
Argument String = "UNIV ABORTED JOB GS4 VMSDLCEREF 2011/10/25 11:38 0000200 0000000 UNIV56 X vmsdlceref 9999 one two three four five six seven eight nine ten X"
Expects:
V_SEVERITY="9999"
V_INFO="one two three four five six seven eight nine ten X"
I probably misadapted the command. Any suggestions?

echo is compressing/stripping the spaces - try double-quoting the variable (echo "${V_MEM_PARAMETERS}")

Heartfelt thanks CarloM. I would never have got there in a month of Sundays.
