The [[ERROR]] statement is used to simulate a program error or to troubleshoot error handling procedures.


{{PageSyntax}}
: [[ERROR]] {{Parameter|codeNumber%}}


{{PageDescription}}
* Can be used to test an error handling routine by simulating an error. 
* Error code 97 can be used to invoke the error handler for your own use, no real error in the program will trigger error 97.
* Use error codes between 100 and 200 for custom program errors that will not be responded to by QB64.
