When I put #include <ctype.h> at the top of my source file, the compiler finds it. If I add #include <reg688.h>, I get error "can't open file 'reg688.h'". If change it to read #include <philips\reg688.h>, it still can't find the file. And if I put the full path in ( <c:\keil\c51\inc\philips\reg688.h> ) it STILL CAN'T FIND the file. What is this stupid compiler looking for?
Ah, but if a genius is defined as slightly better than a stupid compiler, that may not take - or mean - much :)
