Hello World - Getting Started with T24

Are you looking to develop great modules and local services for T24? This is the perfect place to start with. Let’s start from the basics.

The core banking platform, T24 is developed with INFOBASIC code. This is the proprietary language of Temenos. T24 has the unique compiler to convert the BASIC code to object files with TAFc (Temenos Application Framework c) platform. An another flavour TAFj (Temenos Application Framework java), converts the BASIC to bytecode making it capable to run on any device with the Java runtime installed. The BASIC code remains same for both TAFc and TAFj Platform.

Enough Intro! Let’s say hello to this world,

How the syntax of this basic program looks like,

PROGRAM program_name

all the basic statements reside inside this block

END

Now, it is right time say hello,

PROGRAM HELLO

                CRT “Hello World”

END

Yah, we did that. But, how to run this.

You need T24 deployed in your organisation to compile and run this program. Login to the T24 server using third party tools (command prompt, bash shell, putty or tera term) and you will see the jsh prompt.

jsh ->

In that prompt, create a directory with any name using the command below

CREATE-FILE <directory_name> TYPE=“UD”

After creating directory, copy and paste the program in to that directory.

Commands to compile the BASIC program:

Compilation in TAFc and TAFj are handled by different commands,

TAFc:

BASIC <Current_Directory> <program_name>

The above command will compile the code and convert that to object file.

CATALOG <Current_Directory> <program_name>

CATALOG will rebuild the digital library linking (dll) files.

TAFj:

tCompile <directory_path> <program_name>

tCompile will create a class file.

How to run the program?

For TAFc, just type the program name in jsh prompt as shown below,

jsh-> HELLO

For TAFj, a special command needs to be included before the program name,

>tRun HELLO

This will print “Hello World” in the console.

The same can be implemented as below,

//HELLO – first file

PROGRAM HELLO

                CALL HELLO1

END

//HELLO1 – second file

SUBROUTINE HELLO1

                CRT “Hello World”

END

SUBROUTINE can be called only from the programs. Both the files should be compiled and cataloged properly and running the program HELLO will print “Hello World”.

These are the two ways the same program can be implemented.
