Notes:
$ In Pre-Screen logic for Repeat. From Ispecs, LAST-LINE is always equal to 1.
$ When LAST-LINE appears in a Painter SHOW command, it may be shown as

$ To enter an action for the Component, from the screen.
$ To hold the status of the Component in the LINC database the first character of the
relevant value of MAINT is stored in the database records (A, C,orD only.)
Values (in English) that are valid in the MAINT field in the header line on a Component
screen are listed in the following table. Further details of each action are given after the
table.
