Page 224: Flow Control Tools
Chapter 13: Programming Features 6. Flow control tools The calculator has the common flow control tools such as Goto - Label loop struc- tures, and If-, For- and While-statement clauses for enhancing a program’s efficiency. It also has the capability for subroutines.
Page 225 For variable, initial value, end value [, increment] 07 For commands or multiple statements 08 Next Next • The increment value can be omitted. The default value is 1. • For and Next statements must be placed at the beginning of the line.
Page 226: Other Menus Convenient For Programming
• The Gosub label name must be the same as the Label starting the subroutine. • A Return statement is necessary at the end of the subroutine. When the Return statement is executed, the calculator executes the next line after the Gosub statement. • Up to 10 subroutines can be nested.
