What is BMS mapping?
Basic mapping support (BMS) is an application programming interface between CICS® programs and terminal devices. Creating the map. BMS provides three assembler language macro instructions (macros) for defining maps. This method of map definition is still widely used, and this is the method that is described here.
Which macro is used to define the map?
Map. Map is a single screen format which can be designed using BMS macros. It can have names containing 1 to 7 chars.
What is FSET in CICS?
FSET specifies that the modified data tag should be turned on before the map is sent to the screen. FRSET turns off. the attribute byte; it’s used to transmit only changed data from the terminal. Back to top. appasi.
What type of field do we want to avoid naming in a map?
To prevent this, we use Skipper field or stopper field. A Skipper field would generally be an Unnamed field of length 1, specified after a named field.
What is the full form of CICS?
CICS® stands for “Customer Information Control System.” It is a general-purpose transaction processing subsystem for the z/OS® operating system.
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 is map and Mapset in CICS?
BMS is provided by CICS to help you define and format screens. When you define a screen using BMS, the screen is called a map. 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.
What is CICS LINK?
LINK is used to call the other programs expecting return in CICS environment. When the LINK is coded in the program, the calling program expected the control back from called program. LINK passes the control between the programs from one logical level to the next lower logical level.
What is BMS macro?
BMS macros The syntax of each BMS macro is defined, separating the various operands and options into those appropriate to minimum, standard, and full BMS. When coding, have the title in column 1, the macro in column 10, continuation lines should have * in column 72 and continue on column 16 on the next line.
