For~To~Next

Syntax

For {expression (starting value)} → {variable (control variable)} To {expression

 

(ending value)} : {statement} : ... {statement} : Next : ....

Function

Execution of the statements from For to Next repeats as the control variable

 

is incremented by 1 with each execution, starting from the starting value.

 

When the value of the control value reaches the ending value, execution

 

jumps to the statement following Next. Program execution stops if there is no

 

statement following Next.

Example

For 1 → A To 10 : A2 → B : B ^ Next

 

For~To~Step~Next

 

 

Syntax

For {expression (starting value)} → {variable (control variable)} To {expression

 

(ending value)} Step {expression (step)} : {statement} : ... {statement} :

 

Next : ....

Function

Execution of the statements from For to Next repeats as the control variable

 

is incremented by the step amount with each execution, starting from the

 

starting value. Except for that, this command is the same as For~To~Next.

Example

For 1 → A To 10 Step 0.5 : A2 → B : B ^ Next
A Control Structure Commands/While Statement gWhile~WhileEnd

Syntax

While {conditional expression} : {statement} : ... {statement} : WhileEnd : ....

Function

The statements from While to WhileEnd are repeated while the conditional

 

expression following While is true (non-zero). When the conditional

 

expression following While becomes false (0), the statement following

 

WhileEnd is executed.

Example

? → A : While A < 10 : A2 ^ A+1 → A : WhileEnd : A÷2

Note

If the condition of the While statement is false the first time this command is executed, execution jumps directly to the statement following WhileEnd without executing the statements from While to WhileEnd even once.

A Program Control Commands gBreak

Syntax

.. : {Then ; Else ; S } Break : ..

Function

This command forces a break in a For or While loop, and jumps to the next

 

command. Normally, this command is used inside of a Then statement in

 

order to apply a Break condition.

Example

? → A : While A > 0 : If A > 2 : Then Break : IfEnd : WhileEnd : A ^
A Setup Commands

These commands function the same way as the calculator’s various setup settings. For more information, see “Calculator Setup” on page 8.
