Chapter 11: Programming Features
For
variable, initial value, end value [, increment]
commands or multiple statements
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.
• If the comparisons
variable
>
end value
(
positive
) or
variable
<
end value
(
negative
) are satisfied, the program will end the loop
and go to the line indicated by the Next command.
• Up to 5 For loops can be nested, though if combined with other
types of loops, the maximum nested loop number may vary due
to the memory capacity.
• It is highly recommended that Label and Goto statements are not
used in For loop structures.
While
conditional statements
commands or multiple statements
WEnd
• While and WEnd statements must be placed at the beginning of
the line.
• Multiple While loops can be nested to within the memory capacity.
• Conditional statements are evaluated before entering the While
clause.
• It is highly recommended that Label and Goto statements are not
used in While loop structures.
• Up to 8 while loops can be nested, though if combined with other
types of loops, the maximum nested loop number may vary due
to the memory capacity.
Note: Else clause cannot be omitted when the matching If clause is
contained in a For or a While loop.
