T24 Programming - Getting started with InfoBasic(jbc)

Step 1: WRITE your program

Using any code editor of choice create a file called HelloProg.b on your computer and add the following lines of code:

PROGRAM HelloProg
    CRT "Hello there!"
END

Line 1 we have PROGRAM and the name of our program. This should be the name of the file without extension. In most of cases, we will be writing SUBROUTINE instead of PROGRAM. Subroutines run inside T24 while programs run on jshell.

Step 2: PUSH or Copy your code to T24 Server

Push your source code to the server using git git or ftp (depending on what is available to you. You can also copy and paste your source code into a file on the server with the same name. Make sure the file is created in your local .BP folder (eg. MATHISI.BP)

Step 3: COMPILE your source code file

Use BASIC [FOLDER_NAME] HelloProg.b program to compile your source code:

jsh t24 ~ -->BASIC MATHISI.BP HelloProg.b
HelloProg.b
BASIC_13.c
Source file HelloProg.b compiled successfully

Step 3: CATALOG your program

Any T24 program needs to be catalogued before it can run. Use CATALOG [FOLDER_NAME] HelloProg.b:

jsh t24 ~ -->CATALOG MATHISI.BP HelloProg.b
HelloProg
Object HelloProg cataloged successfully

Step 4: RUN your program

To run your program, simply type the name of the program HelloProg from the jsh prompt:

jsh t24 ~ -->HelloProg
Hello there!

As you can see, our message "Hello there!" was printed on the console.
