LSTERR always equals -1 - Tim_Myth - 13-07-2022

I'm using the code from this post: https://forum.hms-networks.com/t/basic-script-error-handling/67326/13

Code:
ONERROR "GOTO ERROR"

ERROR:
  error_number% = GETSYS PRG, “LSTERR”
  LOGEVENT STR$ error_number%

So far every error number has been -1. This isn't very helpful without knowing what -1 means and if LSTERR is always -1, there's no need to check the value.

Hi,

Can you add line in your script, it should solve your issue:

SETSYS PRG,"RESUMENEXT",1

I could, but I want to catch and fix errors, not ignore them. I think as a temporary work around I will make a LINENUMBER tag and update it in each line of the function. I already use a CURRENTFUNCTION tag to track which function is running. EG:
CURRENTFUNCTION@ =""
LINENUMBER@ = 0

ONERROR "GOTO ERROR:

Function MosquittoInit() 
  CURRENFUNCTION@ = "MosquittoInit"
  LINENUMBER@ = 1
  MQTT "open", "ewon_flexy", "test.mosquitto.org" 
  LINENUMBER@ = 2
  MQTT "setparam", "log", "1" 
  LINENUMBER@ = 3
  MQTT "subscribe", "ewons/test/messages", 0 
ENDFN

ERROR:
  error_number% = GETSYS PRG, “LSTERR”
  LOGEVENT "Error in function " + CURRENTFUNCTION@ + " on line " + LINENUMBER@ + ": " + STR$ error_number%, 80
Some of my functions are dozens of lines long and the entire program.bas is ~1000 lines.

When I use this, the code appears for me, but only once, this is a bug I have reported it to our R&D
