Chapter 13: Programming Features 6. Flow control tools The calculator has the common flow control tools such as Goto - Label loop structures, and If-, For- and While-statement clauses for enhancing a program's efficiency. It also has the capability for subroutines. It is recommended to use If, For or While statements rather than Goto-Label loop structures. To access the flow control tools, use the P B BRNCH menu. 01 Label Label label name Specifies a branch destination for Goto or Gosub. The same Label name cannot be used in two places within the same program. Up to 10 characters can be used for a Label name. Up to 50 Labels can be used in a single program. 02 Goto Goto label name To shift the program execution to a label. 03 If If conditional statements Goto label name or If conditional statements Then commands or multiple statements * [Else commands or multiple statements] EndIf * Multiple statements mean a group of statement lines separated by colons(:) that are evaluated as a single line. Within a second structure it is possible to use the following menu items. 04 Then 05 Else 06 EndIf * Use a comparison operand in a condition statement. * Up to 115 If clauses can be nested, though if combined with other types of loops, the maximum nested loop number may vary due to the memory capacity. 214
