Online
CA IDMS mapping facility (MAPC) screens prompt for specifications that define the screen format (map) for a CA ADS application. Data editing, data conversion, and error-handling criteria can also be specified. The specified criteria are automatically applied to data processed by the map at runtime.
Batch
Alternatively, the batch compiler and utility allow the developer to define and compile maps in batch definition mode. These batch tools are particularly useful when several maps require modification and recompilation.
Note: For more information about the online mapping facility and the batch compiler and utility, see the CA IDMS Mapping Facility Guide.
Defining the screen format
A map in an online application defines the screen format displayed to an end user at runtime. The fields displayed on the screen allow the end user to enter or modify data. The data is then processed according to the instructions contained in the processing logic of the dialog.
The following diagram shows the sequence followed when a map is displayed at runtime. The DISPLAY statement in the processing logic accesses the map load module that is stored in the data dictionary, causing the map to be displayed on the screen. Data entered on the screen is then processed according to the instructions contained in the dialog processing code.
