Comment: how would 16bit or 32bit affect development of app in windows/dos? Do I have to consider these bits before writing an app?

Reply: (edit)The 16 bit developement is a developement where the default integer type, of the language you will use, has the standard size of 16 bit. So the range of numbers it can rappresents is between 32767 and -32678. If you will do a developement of 32 bit application the default integer type, of the language you will use, has the standard size of 32 bit. So the range of numbers it can rappresents is between 2147483647 and -2147483648. So if your applications will use big numbers you had better to choose to develop them with a 32 bit compiler.

Reply: (edit)The difference is the pointer arithmetic
and not the format of the integers. 16 Bit compilers also provide you with 32 Bit integers - pascals "longint" for example.
For future compatibilities its more recommended using 32Bit compilers.
Windows 2000 already wiped out some 16 Bit DLLs.
