Backpaging Capability

Definition

The backpaging specification for a dialog or program determines whether the terminal operator can display a previous map page during a map-paging session. The following considerations apply to the backpaging option:

If backpaging is allowed (default), detail occurrences of previous pages must be retained during the map-paging session.
If backpaging is not allowed, the previous page of detail occurrences is deleted when a new map page is displayed.

How to Enable Backpaging

Backpaging is enabled/disabled for a CA ADS dialog or application program by one of the following specifications:

Language	Option/Clause
CA ADS	BACKPAGE(YES/NO) option—Map Specifications screen in ADSC
COBOL or PL/I	BACKPAGE/NOBACKPAGE clause—STARTPAGE statement
Assembler	BACKPAG=YES/NO clause—#STRTPAG macro
