OVERFLOW condition

Status
OVERFLOW is enabled throughout the program, except within the scope of the NOOVERFLOW condition prefix.
Result
The value of such an invalid floating-point number is undefined.
Cause and syntax
The OVERFLOW computational condition is raised when the magnitude of a floating-point number exceeds the maximum allowed.

The OVERFLOW condition differs from the SIZE condition in that SIZE is raised when a result exceeds the declared size of a variable, while OVERFLOW is raised when a result exceeds the maximum allowed by the computer.

If the OVERFLOW condition is raised and it is disabled, the program is in error.
