Symbolic map shows how the variables r defined
physical map is the load module to be displayed as screen

HI ,

regarding TSQ & TDQ........

its like they are temporary storages for holding up ur records that need to be proccessed.. they are not physically stored mostly thats the cocept of temporary storage.....the processing is also much faster for the queues as they are available readily in main memory when the application recollects them.........

theres a big difference between TSQ & TDQ.........in TDQ.. the record is deleted from the queue once it is read but whereas it does not happen with TSQs.............

give a reading on CICS Handbook - Kageyama..

TSq -> Its like a scratch pad, This will not go to permanant memory
unless you explicitly specify.
This is used if you have page up/page down logic in your CICS
screens.
Program A calling Program B which selects db2 rows, So in
program B you can write all your rows fetched to a TSQ and
come back to program A, now you can read these rows from TSQ
rather than going to Db2 every time.
If you have large amount of data to be passed between to tasks
of a transaction you can use TSQ.

TDq -> if you want some processing should happen depending on the data that you have read from the screen for example.

user wants to print the screen, take the information write it to a TDQ
this will trigger a transaction which does the printing.

Trigger level tells n indicates, after nth record is written to a TDQ it should trigger the transaction associated with it.

TDQ has to be defined prior to use.

let me know if you need more with examples.
