An attempt was made to:
•
Execute a code word that is not an instruction.

fault occurs for one of the following reasons:

The result of a signed arithmetic operation could not be represented with the
number of bits available for the particular data type.
•
An division operation was attempted with a zero divisor.
5
A stack overflow fault occurs if:
•
An attempt was made to execute a procedure or subprocedure whose local or
sublocal data area extends into the upper 32K of the user data area.
