Also, the issue I most commonly see is the difference in size for "long" data type. On 32 bit sizeof(long)=sizeof(int)=32, but on 64bit sizeof(long)=64 while sizeof(int)=32. This reverses a formerly safe practice of using long for 32 bit (and insuring the code compiles correctly on 16 bit machines). best Vladimir Dergachev > > > > good luck. > > > > Hin-Tak Leung > > Good advice.
