What is Mapset?
What is MAPSET? Collection of MAPs is called a MAPSET where it can contain one or more MAPS in it. All these are link edited together to form a single MAPSET.
What is the difference between physical map and symbolic map?
The physical map set contains format information in encoded form. CICS® uses it at execution time for constant fields and to determine how to merge in the variable data from the program. Symbolic map sets are typically stored in the library your installation defines for source code that gets copied into programs.
What are the map definition macros for Mapset map fields?
The DFHMDI macro defines a map within the map set defined by the previous DFHMSD macro. A map contains zero or more fields. The DFHMDF macro defines a field within a map defined by the previous DFHMDI macro.
What is a symbolic map?
A Symbolic Map is a Copy book in the library. The Copy book is used by the CICS application program to send and receive data from the terminal. It contains all the variable data which is copied into program’s WORKINGSTORAGE section. It has all the named fields.
What is MDT in CICS?
The modified data tag (MDT) is the bit in the attribute byte that determines whether a field should be transmitted from a terminal to CICS®. The MDT for a field is normally turned on by the 3270 emulator (the CICS cicslterm and cicsteld processes) when the user enters data into a field.
What is IC CICS?
IC – Insert cursor. The cursor will be positioned in this field. In case, IC is specified more than once, the cursor is placed in the last field.
How do I create a symbolic map in CICS?
Generating Symbolic Map
- select the BMS file with the file extension as . bms. Then click Generate > Symbolic Map.
- In the Generate Symbolic Map window, select a folder as the target to keep the generated symbolic map. Enter a file name in the Name field. Click OK.
What is Dfhmdi macro in CICS?
DFHMDI abbreviates as Defined Field Hierarchy Map Definition Interface. The DFHMDI macro defines a map within the map set defined by DFHMSD macro. A map contains zero or more fields. It is a partition definition. DFHMDI used to define a map with its characteristics in MAPSET.
What is meant by Mapset in CICS?
A collection of screens is called a mapset. Both physical (used primarily by CICS) and logical or symbolic maps (used primarily by the application program) must be created. To create the original map definition, CICS provides assembler-language macros for use under BMS.
What is EIB in CICS?
Execute Interface Block (EIB) is a control block which is loaded automatically by the CICS for every program. It contains information about transaction identifier, time, date, etc., which is used by the CICS during the execution of an application program.
