Andy, I tried your suggestion, but I get some errors.
After pasting this code below in my .h header and compile I get an error message saying,

error c129 missing ';' before 'char'
When I click on it, it takes me to PUBLIC char tom; which is the third line from bottom to top.
I will keep trying to get rid of it. All code has been pasted on where you suggested.

main.h
// "Public" Symbols from main.c

// Decide whether "PUBLIC" is to provide a definition or a declaration
#if defined DO_MAIN_DEFINITIONS
// "PUBLIC" is to provide a definition
#define DOC 
#else
// "PUBLIC" is to provide an extern declaration
#define DOC extern
#endif

// Now the "Public" Symbols

PUBLIC char tom;
PUBLIC int  dick;
PUBLIC long harry;
