Notice

Instruction Behavior

The NEXT instruction behaves as follows:

• Instructions within the bounds of the FOR ~ NEXT instruction are executed n times.
  • When the loop ends, the instruction after the NEXT instruction is executed.
• Nesting FOR ~ NEXT instructions is possible up to 16 nests.
• The FOR ~ NEXT instructions must be used in pairs.

Excessive Use

If the FOR ~ NEXT instructions are used excessively, the scan time increases.
The system might be overloaded causing the CPU to shut down or initialize.
