Problem:

Results differ when running INT code versus GNT.

Resolution:

One thing that can cause differing results is the presence and use of an invalid numeric item in a computation. Sometimes programmers find it convient to execute INT programs using the -F runtime switch, this diaables error reporting for unitialized or otherwise invalid numneric data.

In GNT code the default behavior is to assume that all numeric items contain valid data, there is no error checking enabled. This can cause the results of computations or arthmetic operations to differ from the results observed in INT code. To enable error reporting for GNT code, compile the the program using the NUMCHECK compiler directive, this will cause an error when invaid numeric data is encountered
