Once again I have to remind that TDL is domain specific language and its Tally’s programming language which help you to customize your default tally reporting, menu etc. It is very easy to learn tally but you need to have great hands of practice to learn the same.
There is no book available in the market to learn this programming language!
Below is a programming code which will help to create a new field in your ledger Master creation/alteration mode.
;; user who are interested can learn tally tdl,
[System: UDF] MyUDF: String: 1000
;;Modify Ledger Master entry screen and add a line
[#Part: LEd Other Details] Add: Line: MyLine
Local: Field: Short Prompt: Set as: “City: ” [Field: My Field] Use: Short Name Field
;; End of code
In the above code what we have created is known as UDF (User Defined Functions)
The above code will create a new field namely CITY in your default ledger master
On the same way, you can create any other such UDF you wish so.
The screen shot is as below
Try to create such more UDF yourself. I am always there to help you in case of need.
