gui screen beyond 80 character

Can the webfacing, newlook, and other products that leave the 
dds & rpg intact handle up to 132 column (or more) on the display?

A customer is planning a large expansion of certain 
fields in there database (part# from 17a to 40a), etc. 
This is beyond the 80 column they use, and would cause major 
redesign of many 100's of screens. This project (as usual) is 
to be done as quickly/cheaply as possible and in usual 
management fashion is not keen on higher cost for longterm payback. 
Data entry is keyed or scanned. Few remaining dumb terminals will be replaced.
This product needs also to run on small model 800 servers.
