It is basically developed in assembly language which is a low-level language. However, its uniqueness lies in the fact that it is self-contained, executable, and does not require the ROM. GW-BASIC is very suitable to program or code simple games, virtual business applications, and other similar developments.
Its inclusion in the majority of the MS-DOS made it a reasonably affordable source for many ambitious programmers to learn basic computer programming. You can read the detailed documentation from the other sources.

Once you have loaded and initialized on your computers, an Ok prompt is displayed on the screens which indicates that GW-BASIC is now at the command level and is ready for your commands. From this point, you can use one of the two modes of it i-e direct and indirect mode. Direct Mode executes the commands and statements as they are entered. It is able to display the logical operations and arithmetical results immediately and can also store them to be used later.
Direct mode is good for debugging and for calculation so users can quickly compute figures without requiring a complete program. Indirect mode instructions are lost once they are executed. Indirect Mode is utilized mainly to enter programs and in this mode Program lines always follow the line numbers and these program lines are stored in memory and are executed when the command RUN is entered.
Keywords contain some special keywords that perform some actions on call. Commands and statements, both are instructions that can be executed. The difference between both entities is that commands usually are executed in direct mode or on command level.
They are generally used for program maintenance including loading, editing, or saving. In functions, we have multiple types of functions. Numeric Functions are mathematical calculations. While String Functions are strings based. Variables are particular groups of alphabets and numeric that are assigned with values and provide information when they are executed. In nutshell, GW-BASIC and programs developed with it have almost complete access to the host computer therefore, users should treat them by keeping in mind that relevant and appropriate cautions are necessary.
For instance, users are recommended to not do run a program from the internet without first inspecting the source completely. All program lines must be numbered, all nonnumbered lines are considered to be commands in direct mode to be executed immediately.
The format of program source files is normally binary compressed with tokens replacing commands, or optionally ASCII text form. The default type for undeclared variables not identified by such typing statements, is single-precision floating-point. Since the cassette port interface of the original IBM PC was never implemented on compatibles, cassette operations are not supported. PLAY "edcdeee2dfedc4". More low-level control is possible with the SOUND statement, which takes the arguments of a hertz frequency and a length in clock ticks played through the standard internal PC speaker in IBM machines.
Consequently sound is limited to single channel beeps and whistles as befits a 'business' machine.
