I'm using MPLAB 3.12 on a 75MHz Pentium running Win95. Entering code directly into the editor works fine. But I have never been able to get anything to compile without errors when it's imported via the "edit project" window. This is true even though the asm file is saved as text only. There seem to be two cases, with different types of errors. In one case, the error file shows 108 "Illegal character" (followed by an empty parentheses) and 125 "Illegal condition" EOF (even though there is no character visible at that position); and 131 "Processor type is undefined" (but it's in the include file). In the other case, it usually chokes on every line, with a Warning 205 "Found directive in column 1" and an error code 122 "Illegal opcode". I have a much older machine that's successfully running MPASM and programming parts with a PicStart 16B. If I copy one of those asm files and try to use it in MPLAB, one of the above problems will happen when I select "Build All" in the project menu. Anybody have an idea what's going wrong? Reg Neale
