Understanding QBASIC

QBASIC stands for Quick Beginners’ All-Purpose Symbolic Instruction Code. QBASIC is one of the most popular high-level programming languages.

Now let’s have a look at a basic example to understand some of the basic statements used in QBASIC.

CLS
PRINT "HELLO WORLD";
END

CLS is used to clear the output screen.
PRINT is used to display output messages to the screen.
END represents the termination of the program.

Use of comma(,), semicolon(;) and single quote(‘)

QBASIC uses characters like commas, semicolons, and single quotes for various purposes. Comma(,) is used with input and print statements to provide a tab of spaces while a semicolon(;) is used to keep the cursor at the current position. Similarly, a single quote(‘) is used to write comments in QBASIC. These characters will be discussed in other examples too.
