LOOP

Loop

Program Structure

Purpose

Define the start of a block of instructions to be repeated several times. A REPEAT
statement must mark the end of the block of instructions. The count (LOOPINDEX)
may be changed during execution.

Syntax

LOOP

count

Specifies the number of times the statements between LOOP and
REPEAT are execute. The loop count must be between the range
of 0 to 65535. Count may be a nonvolatile variable Gn, a volatile
variable Vn, a system variable, or a mathematical expression.

Remarks

If count is 0 the statements in the loop will not execute.

A loop count specified as a variable is tested for valid range (0 to 65535).

The LOOP statements cannot be used in Fkey or Scanned Event routines. If a subrou-
tine is called from a LOOP, the subroutine may not contain a LOOP.
