Agent Set Input/Output

Input:            SCROLL REQUEST
 
                  MUnnn+
                  MDnnn+
                  MU+
                  MD+

The primary action code for a terminal initiated scrolling request = M. The secondary option codes U, D, allow the terminal operator to move the display up (U) or down (D) a specified number of lines. The maximum number of lines that can be specified with a MD or MU request is 999. The absence of a numeric value implies one line only.

Output:           SCROLL REQUEST
 

The output will consist of the requested scroll segment or one of the following messages:

                  INVALID REQUEST
                  INVALID FORMAT
 
Input:            PAGING REQUEST
 
                  PUnnn+
                  PDnnn+
                  PT+
                  PB+
                  PU+
                  PD+

The primary action code for a terminal initiated paging request is P. The secondary option codes U, D, B, T allow the terminal operator to move the display up (U) or down (D) a specified number of pages, or to move to the first page of a display (T) or to the last page of a display (B). The maximum number of pages or screen panels that can be specified with a single PD or PU request is 101. Absence of a numeric value implies one page only.

Output:           PAGING REQUEST
 

The output will consist of the requested page display or one of the following messages:

                  INVALID REQUEST
                  INVALID FORMAT
 
Input:            MAP FILE LOAD/UPDATE
 
                  ZAMAP+
 

This command, which initiates the map file load and update phase of this package, must be entered from a CRAS terminal only.

Input:            MAP FILE LOAD/UPDATE
 

When the map record files have been updated or loaded, the following response is output to the initiating terminal:

                  MAINT COMPLETE
 

If errors have occurred during the processing sequence, the message(s) will appear on the RO CRAS device.

Tape Input/Output

Offline Terminal Map File Creation

The primary input source for the creation of map record items is the map source statements residing in the user created Map Source Statement Library. Control information is provided on card input and indicates whether processing is to be in an update or a create mode. If the former, card input will supply the information indicating whether the update is of an add, delete, or replace type. The offline segment of the Map File Create And Load Program (03-ASL) constructs the Terminal Map Records, which are sorted using the Sort Utility, and written to the Map Macro Tape File (AS0MP).

Online Terminal Map File Load

The source of input for this processing phase is the Map Macro Tape File created offline. The information provided on this tape indicates whether processing is to be a complete file create/replace or a partial update of existing files.

Other Input/Output

Mapping of data streams is initiated by a requesting user program. The user creates a map parameter list, which includes the selected map sequence number and 3270 command and control characters, as input to this package. After the data stream has been mapped and formatted, this package either returns the formatted data to the user or routes the formatted data to a user specified destination.
