How a data in physical and symbolic map gets treated/mapped?

[harish123]

Hi,

As the physical map is about the screen alignment and the field positions, how the values entered in the field which has PICIN or PICOUT clause in Physical map gets mapped?

Does that mean data sent/received to the physical map should be constant?

How does the data in Symbolic map gets converted with 5 suffixes namely F,L,A,I and O.

For example EMPNO is treated as EMPNOI, EMPNOO, EMPNOA, EMPNOL and EMPNOF. How does this happen in symbolic map?

I read about it but I'm confused about this and so the post.

1. Data sent / received with maps does not have to be constant. Variables work since the contents of the variable are placed into / read from the map fields.

2. Generate a map, compile the program using the copy book, and much will be clearer. The map compile generates the appropriate -I, -O, -A, -L, -F subscripts for named map fields automatically.

3. Values are not mapped -- fields are mapped. Values are the data stored in the field. PICIN and PICOUT merely describe the data and provide the context for understanding / editing the data.

Thanks Robert.

Should I say, this is just kind of a rule?
