The right side of the Contents screen contains hyperlinks to information
about the BASIC programming language.
 
Topic                          Summary
 
◄Functional Keyword Lists►     Display most of the BASIC keywords in groups
                               according to common programming tasks, such
                               as constructing a loop, defining a procedure,
                               getting input from the keyboard, or writing
                               data to a file.
 
◄Syntax Notation►              Shows how to read the syntax information that
                               is displayed in the on-line help for BASIC
                               language keywords.
 
◄Fundamental Building Blocks►  Gives the rules for composing BASIC program
                               lines character by character. Also lists the
                               special meaning of some characters (such as %,
                               !, or #) in a BASIC program line.
 
◄Data Types►                   Summarizes the advantages and disadvantages of
                               using different data types and data structures
                               in your programs.
 
◄Expressions and Operators►    Shows how to combine program variables into
                               expressions that calculate values, compare
                               values, and build new screens.
 
◄Modules and Procedures►       Shows how to combine relatively short,
                               easy-to-understand modules of program text
                               into programs.
 
◄Selected Programs►             A set of 10- to 20-line program modules that
                               do things programmers often want to do--such
                               as creating and writing to a data file.
 
◄ASCII Character Codes►        These tables display values that programmers
◄Keyboard Scan Codes►          often need to include in their programs.
