Yes, @ERROR is set to the exit value of the program called. Quote: And, can i set @ERROR myself in a function? If i create an UDF for example. Yes. You will see that most UDFs exit by using "Exit n", when "n" is the value to set @ERROR to. For example: Code: Function myUDF() Exit 3 EndFunction This will leave @ERROR set to 3. You should always set @ERROR when leaving a UDF, use "Exit 0" for success. You can also set @ERROR in-line by using exit. To clear an error status: $=Execute("Exit 0")
