Description

Paging type

NOWAIT WAIT RETURN

Specifies the runtime flow of control when the user presses a control key, as described in the previous table.

Backpage

BACKPAGE YES

Allows the user to display a previous map page. The runtime system maintains the resources that describe the detail occurrences of previous pages.

 

BACKPAGE NO

Prohibits the user from displaying a previous map page. The runtime system deletes all previous pages of detail occurrences when a new map page is displayed. The lowest page number is the first page that has not been deleted.1

Paging mode

UPDATE

Specifies that the terminal operator can modify map data fields, subject to restrictions specified in the mapping facility and by map modification process commands.

 

BROWSE

Specifies that the user can modify only the $PAGE and $RESPONSE fields of the map. Map fields can still have their MDTs set in the map definition or by map modification commands.

Note:

1 On mapin from the terminal when backpaging is not allowed, if $PAGE has been set to a value greater than the current map page, the runtime system flags all map pages below $PAGE for deletion. When the map is displayed again, these flagged pages are deleted, even if $PAGE has been modified to a lower value in the interim.
