Im on a new computer, trying to use the A51 assembler. In a command prompt window, I can type "A51 some_file.asm" and the assembler will load, however, it will give me a fatal error with the error being an unknown control. I am not using any control directives but when I do, I still get the same issue. My path and environment variables (C51LIB and C51INC) were set to the directory where they were installed, am I missing something?
I am not using any control directives
How did you ensure that? And how is anybody supposed to help you with that without you showing an actual source file that did produce that effect, and the actual error message, exactly as it appeared?
