In all there are 14 arguments. The first 12 arguments are variable in length but are separated by single space characters, so they pose no problems.
Arguments 13 and 14 are optional, when not populated they are padded with spaces.
Argument 13 is 4 characters longs and Argument 14 is 50 characters long.
So expected results are as follows:

Case 1:
V_SEVERITY=""
V_INFO=""

CAse 2:
V_SEVERITY="3333"
V_INFO=""

Case 3:
V_SEVERITY=""
V_INFO="123456789012345678901234567890123456789etc"

Case 4:
V_SEVERITY="9999"
V_INFO="one two three four five six seven eight nine ten X"

Hope that has lifted the confusion?

Actually, it doesn't matter.

Try this...
Code:
V_SEVERITY=$(echo $*| awk 'NF>=13{if(length($13)==4){print $13}}')
V_INFO=$(echo $*|awk 'NF>=13{print($14)?substr($0,index($0,length($13)==4?($14?$14:$13):$13)):
length($13)==4?"":$13}'

Actually, if you have gawk you can just use match (which doesn't have to rely on the values, you can just grab the last 2 fixed length fields). Something like:
Code:
# cat xx.txt
UNIV ABORTED JOB  GS1 VMSDLCEREF 2011/10/24 11:59 0000183 0000000 UNIV56 X vmsdlceref
UNIV ABORTED JOB  GS2 VMSDLCEREF 2011/10/24 12:08 0000184 0000000 UNIV56 X vmsdlceref 3333
UNIV ABORTED JOB  GS3 VMSDLCEREF 2011/10/24 12:12 0000185 0000000 UNIV56 X vmsdlceref      12345678901234567890123456789012345678901234567890
UNIV ABORTED JOB  GS4 VMSDLCEREF 2011/10/24 12:14 0000186 0000000 UNIV56 X vmsdlceref 9999 one two three four five six seven eight nine ten X
# gawk --re-interval '{ matched=match($0," (.{4}) (.{50})$", myarray); if (matched) { printf ("[%s][%s]\n", myarray[1],myarray[2]);}}' xx.txt
[    ][                                                  ]
[3333][                                                  ]

[9999][one two three four five six seven eight nine ten X]

@CarlM
Pretty neat work Smilie
Honestly, I didn't know that match function took a 3rd argument...

The first 14 arguments are easy to handle because they are separated by spaces
Easy.

Code:
read A1 A2 A3 A4 A5 A6 A7 A8 A9 AA AB AC AD AE AF <"$FILE"

If you read further down the thread you'll see the 13th argument can be spaces, so unfortunately that doesn't work.
