I feel so stupid asking this question, but I am trying to assemble just a few lines of relocatable C167 code that I will manually patch into an existing engine control unit. I've done this before with other CPUs and GNU binutils, but am finding the setup of the IDE difficult despite reading instructions.
This is my simple test file. I added the first two and last two lines to try to get it to assemble, but get ..\loop.a66(3): error A45: KEYWORD NOT ALLOWED IN CURRENT CONTEXT for every single line of C167 code.
