This chapter discusses the process of drawing simple pictures by using sequential performativity statements called action blocks in Turbo BASIC. When using action blocks to program a graphic, it is important to remember that single quote mark (') ind

This chapter discusses parameter lists and libraries observed in Turbo BASIC. A subroutine can have a list of variables, called a parameter list, appended to its name; such parameter lists can be used to pass information back and forth between a subr

This chapter discusses the method of using variables, screen formatting, and arithmetic operations in Turbo BASIC. Variables play a major role in programming. A variable is a name for a location in memory. Such a named memory location can be filled w

This chapter discusses loop blocks structures used in Turbo BASIC. Once an action block has been created, often it is necessary to repeat that action. The structure that causes an action block to be repeated over and over again is the loop structure.

Publisher Summary This chapter discusses arrays. Arrays store collections of data under one variable name. They allow for large blocks of data to be thought of as a single structured object. FOR/NEXT loops can be used to access and manipulate such in
