Each line on the panel represents one data record. You can generate and control the numbering of lines in your data with these commands:

AUTONUM

Automatically renumbers data whenever it is saved, preserving the modification level record.

NUMBER

Turns number mode on or off, and selects the format.

RENUM

Renumbers all lines, preserving the modification level number.

UNNUMBER

Turns off numbering and blanks the sequence number fields on all lines. This deletes all modification level records.
