The USAGE format is the one used to display the field on a report. The ACTUAL format describes how many bytes the field occupies on disk. For alpha fields this is ordinarily the same, but it can and often is different for other formats.

For instance, for a relational table, the ACTUAL may be DATE but the USAGE may be YYMD.

For sequential files and numeric fields, the ACTUAL might be I4 and the USAGE might be I6. A 4-byte field stored as an integer can hold a much larger displayable number than 9999.

I would suggest some reading in the Data Adminstration manual for a more robust discussion.
