Everything I have read about this suggests that the Visual C++ compiler treats the REGISTER keyword with very low priority (i.e. it uses it as a suggestion, but does what it thinks is best.)

I'm sure I still have a Visual C++ 1.52c disk somewhere at home - maybe I should install that (Win 9x?) and see what assembler that generates.

1) As we know that if a variable is declered in a file (Let .c file) then we can access this variable from any other .c file by using "extern" key word...... Now Question is where this extern variable is stored in memory.

2) Is there any way to make this sure that if any variable is declared in some .c file then any other file can not access this variable.

3) where the variables are stored while execution of program (RAM, or Hard disk, or CPU Registers)..
