thanks for your help.

some of the problems i was having was removing the B from the DOB line. along with the B from the Phone nums.

HOME# cat user2.txt
PT: DARRELL SMITH
PTDOB: 12/15/98
RP: DARRELL SMITH SR
PTSSN: 558-55-1234
RPSSN: 554-55-1234
HMNUM: 213-555-1234B
RPNUM: 213-555-1234
POENUM: 213-555-1234B
HMADDY: 123 A yourstreet Los Angeles CA 90504
POENAME:
POEADDY:
CLIENT: TMC
DOS: 05/07/05

After trying many diff things i changed ghostdog's example and viola

awk '//{gsub(/B$/,"")}{print}' user2.txt


and now th results are in

HOME# awk '//{gsub(/B$/,"")}{print}' user2.txt
