Hello TDL : Our First full fledged Tally TDL

you can watch the video and skip reading however reading will also helpful to you.

Hello world is the first ever tutorial lesson to learn Any programming languages. You learn HTML, JAVA, PHP or even Tally TDL almost 90% tutorials will teach you the first tutorials which will print a line on the screen with ” Hello World” So, we will also write our TDL lesson which will print in your Tally screen ” Hello World ”

So, open Tally developer Now.

first thing first. We simply don’t want to print the sentence hello world to anywhere. We want to add a new report in the main menu of Tally

So, what we need is to add a new report for this purpose we will amend the definition of the Main Menu reports

# symbol is used to amend any existing definition of Tally TDL. Remember you can use the # symbol only if a definition is already existed in the Tally.

So the thumb rule is that # prefix to a definition is a modifier symbol

Now, our first code of line will be as

[#Menu:Gateway of Tally]

Here we use # symbol to amend the definition of the Menu Item.

Gateway of Tally is the default menu report in Tally.

Now we need to add codes what we need to amend to the Gateway of tally so, our next coding line will be:

add : Item : Hello TDL : Display : My Hello TDL Report

Here we are specifying add command which tells the Tally compiler that we want to add something so we put Add keywords then we specify what we need to add in our codes

Key item refers to the item name which we want to add

H refers to short command you can specify any other keyword of your choice. Just take care that you don’t use any existing shortcode like V which is already used for Voucher entry, B for balance sheet etc

Then display refers what report to be shown to use. Here we are specifying a new report My Hello TDL when the user clicks this new menu item it will show him the a report namely My Hello TDL

Now we have added a new report in the main menu however we haven’t defines the report what this report will contains We only named it as My Hello TDL so, let’s have fun with our new report

write in your program editor below line of code

[Report: My Hello TDL Report]

Form : My Hello Form

Here we wrote 2 lines. First line defines our newly created report name that is hello TDL Report and second line we added a form namely My Hello Form. Again you can name your form anything  you like. For e.g. you want to name your form as “ NewForm “ then you can do so without any issue.

Now, we need to define a form and then need parts to a form. A form must have parts and parts must have lines hope now you are getting the basic ideas of a TDL program structure

so, write below lines of codes

[Form : My Hello Form]

Part: My Hello Part

[Part : My Hello Part]

Line : My Hello Line

Now we are in the last stage of our first coding program in Tally TDL

Line must contain a field and field is where the actual data or things we need to show

so, let ’s rewrite the line definition again

[Line : My Hello Line]

Field : My Hello Field

[Field : My Hello Field]

set as : “ Hello, Mahendra. Welcome to the Tally TDL world “

save this file as hello.txt

The Ultimate complete code will look like this one

;; this tdl is our first tdl to learn Tally TDL
[#Menu: Gateway of Tally]
Add: Key Item : HelloTDL :H: Display: My Hello TDL Report
[Report : My Hello TDL Report]
Form: My Hello Form ;; We are adding Form to the Report. Every Report must have a Form
[Form : My Hello Form]
Part: My Hello Part
/* We are adding parts to Form. Part Name is My Hello Part. Every Form must have one or more Parts*/
[Part: My Hello Part ]
Line : My Hello Line ;; We are adding lines to Parts. A part may have one or many lines. Minimum one line is a must else the software will
;; throw an error
[Line: My Hello Line]
Field : My Hello Field
;; We are adding fields to the lines.
;; Lines have one ore many fields. Field is the ultimate place holder which
;; holds data to display
[Field: My Hello Field]
Set as: ” Hello, Mahendra. Welcome to the Tally TDL world”
;; This is data which will be shown in Tally in our new report
;; end of the TDL code

now, activate the Tally TDL and see the result it should show in the Tally as per the below screen shots

To activate your TDL in Tally, go to main menu, then press F12,

Then go to Products & Feature Option.(Shut cut command is T)

Now, Press F4

Set yes to enable TDL

Now specify the file path as per the below image :

TDL configration
Figure : TDL configuraiton
Hello Tally TDL
https://tallynine.com

Once you hit that HelloTDL or just press H you will find the next screen as below :

If, your screen shows exactly same then your code is perfect and it refers that you learnt your first TDL program successfully.

Exercise

Excise makes the learning perfect. Let’s play some coding for fun.

Write a Tally TDL which displays the field text as “ I am learning Tally TDL

Report name should be HelloReport

Form Name should be HelloForm

Field name should be MyTextfld

prepare this TDL and save in the shared dropbox for my review mention your name and your mail id in the beginning of the TDL so that I can identify who has prepared the TDL

in Tally TDL, put ;; put as a symbol before any line so that it will be counted as a comment.

For a better understanding,  watch the below video it will give you a clear Idea

If you face any issue, then post your code in the comment section

    Sir I have tried My Hello World, but message is not appearing.

    I have save my file in Dropbox, named Bhavin Vora – Mumbai \ Hello World.txt

    2. Hello Bhavin,

      I checked your code and it is working fine without any issue. Looks like you had not activated your TDL and if you had activated it, you may need to refresh your TDL

      Please contact me over WhatsApp tomorrow morning so that I can help you in activating, refreshing the TDL with your Tally.ERP 9 software

      1. Hi If you are facing any issue please msg me in WhatsApp or in Zopi chat so that I can undersatnd it and can help you. All students who have joined Dropbox their codes are in their name folder and you can access codes of each others. if a student has not joined the Dropbox then you can’t access their codes.

  4. Bhavin Vora says:

    Sir I tried to do exercise but i am getting error T0008: could not find original description for report – “Hello Report”

    1. Hello Bhavin

      $Symbol is a modification attribute of an existing definition

      Not every definition can be an existing definition in our exercise
      Please go through the chapters carefully and follow them line by line

      you can’t put # before every definition

      in our exercise we are modifying only existing definition is the #Menu : Gateway of Tally so it will fetch the #symbol
      but then rest of the definitions are new newly defined
      so, please remove the #symbol from rest of the definitions and I suggest you please go through the chapters carefully

    Dear Sir,
    I did not get message on my tally so please check this code not tell me what wrong with this code . please check drop box and guide me (screenshot)
    code is:

    Line:My Hello Line
    [Line:My Hello Line]
    Field:My hello Field
    [Field:My Hello Field]
    ”Hello,WELCOME TO RELIABLE INSUPACKS”,,

    1. u are not mentioned the key for display the field, add item any alphabet in before display command with colon symbol befor & after the alphabet

      1. It is not mandatory to do so. first purpose is to get ourselves familiar with the new coding so one step at one time we have to learn very basic things in starting and not everything.
        If your code ae not working then let me know.

    1. Hello

      Please follow this chapter carefully

      You need to create a new file in the Developer (Don’t write your code in the Notepad

      In the above chapter, there is a video tutorial also available.

      Create a new File and write code in that file and save that file in D Drive

      once you complete the code, Right click the bottom file name as shown in the video
      Copy the file path and then go to Tally

      Main Menu

      F12
      Product and features

      F4

      in the path just paste the file path

      and hit enter

      Alternatively, please be online and give me the Teamviewer

      Though the chapter and the video are self-explanatory and almost all the students have done that without any issue.

    1. Hello,

      You do not have to share your files with me.

      I have sent you an invitation for the Dropbox Folder. you need to accept that invitation.
      Once you accept the invitation, it will add more than 200 students folders in your system
      Out of that, one folder is in your name.
      Just put your files in that folder and It will be synced to my system immediately.

  12. suhasmasaye says:

    what is default & simple field shown in the Tutorial Video ??

    1. Simple Field is the name of the existing Field in the Tally TDL
      Default is something different.
      If we want to apply some settings to every fields within a line we use the default key word.

    2. I suggest you write the code rather then trying to understand.

      Because TDL is more about writing codes and not to understand them.
      If you write and test your code, you will have a better idea.

  13. ashok.ranisati says:

    Sir when I add path in Tally it shows error message T0001.Let me know why this happens Sir.

    1. Hello Ashok,
      Error number are not helpfull to understand an issue.
      You should quote the full eroor description of the error.
      Those errors are not going to kill us in anyways. So whenever there is an error read it in full and post the full description.

      Most of the errors are self explanatory and it doesn’t need an expert knowledge to solve them.

      So, test it again and do let me know the full error description.

    1. ; is symbol of of disabling the codes means whatever you write after the symbol ; won’t have any effect in our code. it will be totally ignored.

      Actually it is ; and not ;; but as a fact of habit, I use it ;; it’s a personal choice.
      Generally it is used to disable any code or to put comments in our codes.
      And also you will find a separate unit about commenting the codes.

  16. I have dropbox. Please send me link where I can save code.

    Hello Sir,

    Your remarks will be highly appreciated.

    Thank you very sir.

  23. ravindrakhadke says:

    what is the use of invisible command ?
    how can i know the different commands and their use and where to use in tally TDL

    1. did you tried using invisible?

      as the name suggest invisible means simply it will not be visible.
      Generally it is used for logics if condition A is false then then condition B will not be executed
      We are already using invisibles in F11 yes/no settings where when we set a condition to yes it will give us another pop up like GST details of a company
      So for those things we can set no /invisible when the first condition is set to no

      You can’t get a ready made list you can know then only by writing codes and making yourself familiar with codes which you can do by following the course.
      You will not get a ready made some magical list of things anywhere in TDL
      only solutions is keep studying the course and make yourself familiar with the codes.
