Hi, Quick question, whats wrong with:



...

91: #define TEST(a) #a
92: TEST(int b);

...

I expect it to substituted by



...

92: int b;

..

but my MSVC 2005 compiler complains about 1>.\Source\main.cpp(92) : error C2059: syntax error : 'string' Thanx a lot, Dietger

It turns whatever argument you pass into a string so it'd be "int b"; instead of just int b;
There is an option for the preprocessor to output the preprocessed source file, this way you can easily "debug" what's going on.
