Explanation

The following text explains the meaning of each construct:

OLAYINFO

Analyzes the overlay structures and ASD table to determine if there are any problems with the overlay structure. The following options can be used in combinations; only the capitalized portions of the options need to be entered.

OLAYINFO OVERLAY OLAYINFO OLAY

Displays the outer level of the overlay structures. OVERLAY and OLAY are synonyms.

OLAYINFO FILE

Displays the subfile structures within the overlay structure.

OLAYINFO CLIST

Displays summary information about the linked list of all overlay areas.

OLAYINFO AREA

Displays summary information about the areas linked into various parts of the overlay structure. This command is meaningful only when combined with the OVERLAY, FILE, or CLIST options.

OLAYINFO DETAIL

Displays greater detail for the structures being displayed. This command is meaningful only when combined with the OVERLAY, FILE, or CLIST options.

OLAYINFO AREADETAIL

Used in combination with the AREA option. This provides complete detail on the displayed overlay area structures.

OLAYINFO NOCHECK

Skips time-consuming processor check on the ASD table.

OLAYINFO ALL

This is shorthand for the following combination of options: OVERLAY, FILE, AREA, and DETAIL.
