To get a little more room on my machine, I moved MPLAB to a network drive elsewhere in the shop, while keeping the project files on my hard drive. My code, which assembled before, includes the include statement below. The help files say this should work as a fully qualified path. However, I keep getting errors that the file c:\mplab\p16c74a.inc could not be found. I note that my file originally had the include as #include, but the current help file does not have the #. It doesn't seem to make much difference whether it's there or not. For fun, I tried commenting out the line and still got the same error message. Is the assembler trying to find the include file based on the list p=16c74a? How can I get this to look for include files on drive J:? Thanks!
