Q: In my DDS, I have defined a field using the REFFLD. The field that is being referenced is defined with a length of 12 with three decimal positions. I would like the new field to have zero decimals. Is there a way to reference a field and change or truncate the decimals? I tried zero in the decimal field, but this just moved the decimal point. When the report prints, it shows 13000, not 13.000.
A: You cannot truncate the decimals directly using DDS. The technique I recommend uses a data structure as shown in 4. The data structure defines the first nine positions of the 12-position field (DATA) as the new field (D@DATA).

In this situation, the only real advantages to using REFFLD are that the field text will be shown on the compiler listing, and it's a little easier to tell what's happening when you look at it again a year from now. 5 illustrates the DDS you could use to define the new field. Editing keywords may be inappropriate with the new field length and decimal positions. They can be overridden with the DLTEDT keyword.
