The following program produces differemt results with gcc and
the 2.0.1 386/ix C compiler


#define ctl(a) ('a'&037)

main()
{
printf( "%d\n" , (int) ctl(a) );
printf( "%d\n" , (int) ctl(b) );
printf( "%d\n" , (int) ctl(c) );
printf( "%d\n" , (int) ctl(d) );
}

As the above #define construct is used ny the sc spread sheet, I 
assume someone has already pointed this out.
