ABB Error Handling RETRY from start of procedure

I have a search routine that consists of a number of SearchL instructions. Occasionally I will get the ERR_SIGSUPSEARCH error where the signal is already high (or low) when the search starts.

I am attempting to include error handling where if this error happens, the robot should retry the entire procedure. However I have only been able to find the RETRY command, but this just restarts the program at the search where the error happened. Does anyone know of a way I could retry the entire procedure? I attempted to do a GOTO from the error to the top of the procedure but this is not allowed.

Thanks.

Worked perfectly. I assumed RAISE could only be used for user created errors.

Thanks for your help.
