For ~ To ~ Step ~ Next (COMP)
Syntax For <expression (start value)>
→
<variable (control variable) >
To <expression (end value)> Step <expression (step value)> : <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 : A

B : B

Control Structure Commands: While Statements
While ~ WhileEnd (COMP)
Syntax While <conditional statement> : <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 : A
2
^
A + 1
→
A : WhileEnd : A ÷ 2
Note • If the condition of the While statement is false the fi rst time this command
is executed, execution jumps directly to the statement following WhileEnd
without executing the statements from While to WhileEnd even once.
• To input the WhileEnd command, select “W·End” on the function menu.
Do ~ LpWhile (COMP)
Syntax Do : <statement> : ... <statement> : LpWhile <conditional statement>
Function The statements from Do to LpWhile are repeated while the conditional
expression following LpWhile is true (non-zero). Since the condition is
assessed following execution of LpWhile, the statements from Do to LpWhile
are executed at least once.
Example Do : ?
→
A : A × 2
→
B : B
^
LpWhile B > 10
Note To input the LpWhile command, select “Lp·W” on the function menu.
