GW-BASIC Direct Mode & Indirect Mode – GW-BASIC Tutorial

GW-BASIC direct and indirect mode

-Modes of Operation in GW-BASIC:

GW-BASIC can operate in two modes, Direct Mode and Indirect Mode. These modes will be discussed below:

1) GW-BASIC Direct Mode:

“Direct mode of GW BASIC executes the commands as they are typed.”

Arithmetic and Logical operations results can be calculated at the spot, but after the calculation/execution, the commands are lost. Below you will find an example of GW-BASIC Direct Mode:

As you can see at the above GW-BASIC screenshot, the commands are executed as they are typed, without any sequential instructions. Other than this, once they are executed, they are lost. They cannot be used/executed again until we type them. So in conclusion, this mode is useful for quick computations and for debugging purposes.


2) GW-BASIC Indirect Mode:

“Indirect mode of GW Basic is used to type programs.”

Program statements are always followed by line numbers, and they are stored in the memory. When they are loaded in memory, we can run the program by using the “RUN” command. Check the following example screenshot of Indirect mode for more clarification:

At the above screenshot, the program is temporarily loaded in the memory and is executed, which is Indirect mode of the GW-BASIC.

    I am using AUTO command in GW BASIC. After type a program I want to run it. END command not returning me to the Command Level to execute the RUN command. I also tried CTRL-BREAK and CTRL-C. GW BASIC version is 3.23

      CTRL + C should work with all the GW-BASIC versions. Are you sure that you are only pressing these 2 keys and not any other key with them?
