Explanation:

DCHAR is a macro, which is expanded by the preprocessor.
TCHAR is a synonym for a pointer-to-char type.

After preprocessing, the code fragment expands to:

char* ch1, ch2;
TCHAR ch3, ch4;

which is perhaps more clearly written as:

char *ch1, ch2;
TCHAR ch3, ch4;

which is equivalent to:

char *ch1; char ch2;
char *ch3; char *ch4;
