EVALUATION OVERFLOW IS LINE XXX

If the error message Evaluation Overflow is received when editing program, there is not sufficient memory dimensioned for the program.

-Check with the MEM command
-Re-dimension program with more memory if necessary.

Another possible cause of this error is a GOSUB without a RETURN.

As the program runs, the free program memory is used up as the GOSUB puts line numbers in the controller push down stack. When the available memory reaches zero, the program will give an evaluation overflow error.

This can take a variable amount of time depending on the amount of available program memory and the number of times the GOSUB is called.

Ensure each GOSUB has a RETURN.
