I think this technique was common before subfiles were available. Maybe 36
days. All the fields that are normally displayed by a subfile would be a
matrix of fields in a single format. If there are input fields in a header,
they'd be included with these in the same format.

What you don't get is the READC (read changed subfile record).You need to
check all the fields in your array (matrix) for change.

Doable, just more work. You'd different field names for each row. Or you
could use the COBOL equivalent of RPG's multiple occurrence data structure
(is there one? 2-dimension array?). You might need separate processing
branches for each row (not with MODS or 2d array?), etc.
