All is working as it should. Using any of the allowed field statement   
options which imply numeric data (such as NUMERIC, BWZ) will indicate to   
Quick that it should treat the field as numeric. It will change the value   
in fieldtext by right justifying and zerofilling it so if you consider   
fieldtext to be a "buffer" then, yes, Quick does change the value. It   
will also apply numeric edits to whatever the user enters -- e.g. it will   
disallow alphas in the field.

As to whether it is stored in FIELDTEXT or FIELDVALUE, I would rather you   
consider that it is in FIELDTEXT during the INPUT and OUTPUT procedures   
regardless of datatype and then use the actual item name in the EDIT   
procedure and let Quick do the mental exercise of substituting for the   
buffer. For the record, though, it is actually in FIELDTEXT since it is a   
character item.
