This is embarrasing, I've forgotten how to run SBASM
I remember I had to prefix the SBASM command it with the python interpreter name which I cant remember... All those nights spent on KB+ and its gone
Edit: I remember now, I changed my PC, I never installed SBASM on the new one, just copied it across, I'll have to study Sans page again as I dont think I have the python interpreter installed on the new one
?
