EDTFIL Device Function

The Edit File (EDTFIL) function defines a program to maintain records in a file, many at a time, using a subfile. The subfile is loaded a page at a time when you press the scroll keys.

For each key field on the subfile record, there is an equivalent field on the subfile control header format. Key fields can be used as positioner parameters in the subfile control format to specify which fields are displayed in the subfile. The subfile has, by default, all records in the access path as input-capable.
