I am finally getting my act together and playing with these PICs. I am using Linux at home. I use mpasm under a DOS EMU environment. All seemed to be working untill I tried using the INCLUDE statement. It seems no mater what syntax I use I always get a : Cannot open file (Include File "G:\MTTEST\P16C84.INC") I have tried all of these syntax methods (and more) #include "P16C84.INC" #include "g:\mytest\p16c84.inc" include include "G:\MYTEST\P16C84.INC" Here is my setup: Linux 2.0.33 dosemu 0.66 mpasm 2.01 Is there anyone out there using mpasm under a dosemu environment. I am open to other options when it comes to compiling under Linux as well. I use picprog as my serial port burner and a LudiPIPo programmer.
