Turbo Basic - Code Example

Code Example

The following program is an example of the ALGOL-like BASIC dialect that Turbo Basic supported. Unlike traditional BASIC, which used line numbers and had limited control structures and no support for ALGOL-like subroutines, modern BASIC dialects starting at this period were extended to make the language compatible with modern structured programming theory by discarding the line numbers and adding the control structures and subroutine definitions needed by structured programming.

INPUT "What is your name?: ", n$ PRINT "Hello "; n$ DO s$ = "" INPUT "How many stars do you want to print"; s FOR i = 1 TO s s$ = s$ + "*" NEXT i PRINT s$ DO INPUT "Do you want to print more stars"; q$ LOOP WHILE LEN(q$) = 0 q$ = LCASE$(LEFT$(q$, 1)) LOOP WHILE q$ = "y" PRINT "Goodbye "; n$

Note that s$ is a string and s is a single precision floating-point (number). They are separate variables.

Like the other Borland products of this era, the code executes within the integrated development environment.
