Variables,he information. The information may vary as a program runs. Computers recognize two types of variables, numeric and string. A numeric variable stores numbers; a string variable stores a series of letters, numbers, and symbols as a unit.

Branching Statements,y flow. These action directors come in two forms: unconditional statements that simply redirect program action; or conditional statements that allow two or more responses according to conditions set by the program’s logic. Branching statements include GOTO, GOSUB, ON-GOTO, ON-GOSUB and IF-THEN-ELSE.

Abutment

The FOR-NEXT Loop,loop through the use of counters and the IF-THEN statement. The FOR-NEXT loop is another method that will enable you to form loops and assign values to variables with fewer statements and greater control than the previous method. This is because the FOR and NEXT statements allow for a more concise definition of a loop.

START

String Functions,h as “Hello there!” or “A = B + C.” The last character in a string variable name is always the dollar sign; for example, we could call “Hello there!” A$, or even HELLO$. Strings can be up to 255 characters long. You can link strings together with the ampersand (&). If A$ = “MOTOR” and B$ = “CYCLE,” then A$ & B$ = MOTORCYCLE.

Computing Technology in Autonomous Vehicle,This chapter introduces microcomputers: their structure, methods of storing information, and languages. You’ll find this information useful but not absolutely necessary for understanding how to program your TI-99/4A. If you’re eager to grapple with the machine on your desk, skip right ahead.

https://doi.org/10.1007/978-981-16-4392-7If you’re just starting out with your 99/4A, you’ll find that a cassette deck will give you a handy and inexpensive means of storing and retrieving information. This chapter contains equipment and maintenance suggestions and reviews the program loading and saving procedures for cassette decks.

Advanced Dynamics of Mechanical SystemsAs we saw in the last chapter, commands that can stand alone are also tools for building programs. This chapter will review such commands and their roles in creating and editing programs. (Before beginning, be sure you’re comfortable with the screen editor, described in Chapter 3 and in your ..)

Advanced Dynamics of Rolling ElementsTI BASIC has very precise ways of dealing with numbers. When assigning values to numerical variables, you can represent and enter them in two ways: as “real” numbers (integers and decimals) or in exponential (sometimes called scientific) notation.
