Can any one say me the difference between the Physical map and Symbolic map. Where do we use it in program and in which circumstance do we use it.

Hi,

Physical Map? Screen layout coded in BMS and finally loaded into a load module.
The physical map is the load module, which is primarily used by CICS. It defines maximal data length and the starting position of each field to be read and allows BMS to interpret input NMDS. It controls the screen alignment plus sending and receiving of constants and data from and to the terminal, and has the terminal information.
For output operations, the physical map defines starting position, length, and field characteristics and default data for each field and allows BMS to add Bcc and commands for output in order to construct an output NMDS.

Symbolic Map? Copy library which is copied into the working storage of a program.
It is a copy library member, which is to be included in the application program for defining the screen fields. It is to ensure device and format independence to application programs.

Thanks,
Gau

Hai Gautham

Another doubt...

Physical map will be created by us.
once you compile the Physical map....the Symbolic map will be automatically generated.

Am i right.
