Using the SHOW command in an editor session

The SHOW command in an editor session has the following features:

If you use the SHOW command to show not-selected records, then the prefix area (if displayed) indicates why each record was not selected. For details, see Seeing why a record is not-selected.
If you use the SHOW command to show not-selected records in TABL display format, and the records contain invalid data when interpreted according to the field definitions for the current record type, then the invalid data is shown as highlighted asterisks. Additionally, in Edit, File Manager moves the cursor to the first occurrence of invalid data.

Examples

In SNGL display format, to show only the selected records for the current record type, enter:

SHOW NOT OFF
SHOW SUPP OFF

(or just SHOW ALL OFF)

In SNGL display format, to show all selected records, enter:

SHOW NOT OFF
SHOW SUPP ON

(as you step through the records using the Next function key (F11) and the Previous function key (F10), the field headings change to match the type of the current record)

In SNGL display format, to show all records, enter:

SHOW NOT ON
SHOW SUPP ON

(not-selected records are formatted according to the record type that was current prior to moving to that record).
