JSR Nesting

What does 17 mean?

This error indicates that the nesting depth of subroutines (JSR commands) in the CLM01.3-M user program has exceeded the maximum allowable limit of 127. Excessive nesting can lead to stack overflow or unpredictable program behavior.

• The user program contains more than 127 nested subroutine calls (JSR commands).
• Recursive subroutine calls without proper exit conditions, leading to an infinite nesting loop.
• Complex program structure with excessively deep subroutine layers.
• Logical errors in program flow causing unintended or prolonged subroutine nesting.

Click steps to track your progress.

1. 1

   Review the CLM01.3-M user program to identify and reduce the depth of nested subroutines to ensure it does not exceed 127 levels.

2. 2

   Simplify complex subroutine structures by breaking them into smaller, more independent program blocks.

3. 3

   Ensure all JSR (Jump to Subroutine) commands have a corresponding RTS (Return From Subroutine) command to properly exit subroutines.

4. 4

   Optimize program logic to minimize the need for deep nesting, possibly by re-evaluating the program flow.

5. 5

   Test individual subroutine blocks independently to confirm their intended behavior and ensure proper exit mechanisms.
