What I recall doing in the days was that my LOADable data files always had the two bytes of "default" load address at their beginnings. Whether I used them later on or not depended on the needs but they were there. Situation is of course more difficult if you have to deal with data files created elsewhere. Then the solution given by Oliver seem to be feasible, even if being not extremely "elegant" workaround. Yes, I need other files, not my ones, where I can create a format I prefer. Guys, please be patient, but one more question. What is the best way to do this exactly? 1. JSR SETNAM (with: X/Y=file name, A=filename size) 2. JSR SETLFS (with: A=1, X=content of $BA, Y=0) 3. JSR LOAD (with: A=0, X/Y=buffer address) this is the current one. I guess, I need to set buffer address + 2 for step 3, also I need to insert some more steps betweeen 2. and 3., however I am not sure about that: I need OPEN the file then BASIN two bytes. Do I need to close the file before LOAD then? Won't be LOAD bothered (ZP locations modified etc) that I did OPEN/BASIC/CLOSE/whatever before calling LOAD as I want to use the same params given by SETNAM+SETLFS? And can I use the very same parameters as for LOAD for OPEN too, so I don't need call SETNAM/SETLFS again before LOAD (as far as I know, SETNAM/SETLFS only sets some ZP locations btw, nothing more). Sorry, but I have no experience on I/O: I always wrote programs where no need to do I/O just a basic stub with SYS, and direct HW programming no KERNAL, whatever :) Thanks in advance for the help. ---------------------------------------------------------------------- To unsubscribe from the list send mail to majordomo@musoftware.de with the string "unsubscribe cc65" in the body(!) of the mail.Received on Fri Dec 16 16:51:17 2011
