Thanks for the help, Imre.  You were right, I left NewMode as a local
variable.
void CheckDIPs(int &NewMode) fixes the problem.  I should have know
better...

Hi,

I think you did another mistake. NewMode is a local variable as I see.
Thus, it won't return the value you assign to it. CCS recommends a trick
here: write in the declaration
void CheckDIPs(int & NewMode) {

I hope this helps.
Regards,
Imre
