This is my final code in an attempt to use variables:

Code:
awk 'rec_type1=substr($0,13,4) {$rec_type1=="AM00"} {SUFFIX = substr($0,38,2)} substr($0,13,4)=="AM01" {$0 = $0 FS SUFFIX} 1'  file

it's Not working as expected using variables

Code:
Input Data:
000000000001AM00 1500895700000000000100                                                                                     
000000000001AM01 035000000000013000399820810000000P 

Output Data:
000000000001AM00 1500895700000000000100                                                                                     
000000000001AM01 035000000000013000399820810000000P 98

it's grabbing SUFFIX = 98 for the current record, not from the previous one.

Please help.

Thank you.
