Description
Runtime errors are caused by the program running on the AKD BASIC trying to do something
that is not allowed. For example, runtime errors occur when you attempt to write a value that is
too high or too low to a particular variable. We try to catch as many errors as possible when the
program is compiled, but some errors are only detected when the program is running.
Determine the particular problem causing Runtime Error (F4 Fault) by looking at the value of the
VM.ERR variable. Use the Variables Window to find the value of VM.ERR.
The table below shows what each value of VM.ERR means.
