Maybe he is kidding. He compiled the code with i defined as char or int and then removed the declaration line and then took a screenshot. :lol:

Try a 'clean' first or hit CTRL+F10 to clean and rebuild.

Now i see the problem!!!

Using old version of mplab (like screenshot) 8.5 and HI-TECH C Compiler for PIC10/12/16 MCUs (Lite Mode) V9.70 its is possible!!!

Trying to compile, first click on build, we receive the message:

"Error [192] C:\Temp\MCU\Microchip\PIC16F628A\Blink\main.c; 11.6 undefined identifier "i""

If click again, "********** Build successful! **********"

This occurs because file generated .P1 .

I believe this is why.

Using a new version, its break in error message!!!

P1 is a file generated by compiler... your code is a (p-code) precompiled translated before creating hex file.

Ex: if you project name is test and the source code is main.c, the compiler generate main.pre and main.p1... if the code is ok, he generate the rest:

test.as, test.cof, test.hex, test.hxl, test.lst, test.map, test.obj, test.rlf, test.sdb, test.sym, funclist, startup.as, startup.lst, startup.obj, startup.rlf...

In the manual, may have something about it, or as said before, this is a bug!!
