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?
Thanks Andy. I already found these sites, but there was no helpful hint, or I just didn't recognize it. But meanwhile I found the simple solution:
One directory in my path had more than 8 characters, that was all. So I shortened it and now it works. :D
"One directory in my path had more than 8 characters"
Clearly, 20-year-old tools were never designed to cope with that!
