How do I change a columns contents to something else in the same table.

for example:

in table 99ivpr
data
trans_desc refn01 amount
ANTZ02 ANTZ02 45.00
ANTZ03 east ANTZ03 32.00

trans_desc refn01
changeto ANTZ (combined) %ANTZ%

results
trans_desc refn01 amount
ANTZ (combined) ANTZ02 45.00
ANTZ (combined) ANTZ03 32.00

Thanks
