Is the source code intended for your assembler?
I've checked that the guy who wrote this program is use the MPLAB. So i assume the source code is intended for the assembler as the MPASMWIN is come together with the MPLAB package. The error that appeared was 'Symbol not previously defined' (113 errors), what problem do you think it is? This is my first PIC project, so there are a lots of thing i still learing, hope you understand my situation. thank you mate

Rich (BB code):
One thing to make sure of is that the file referenced in the above include statement is both present on the compiling machine and located in a directory that the compiler is looking in for "include" files.

This file most likely contains the define statements that are needed and not being found during the code compile process.
