Hi, First of all thanks for all the helpful feedback so far... > PRG is probably more special as it has (ar rather is being > expected to have) two bytes loading address at the beginning of the file. I see. So if I type LOAD on a PRG file without a valid loading address the result will be (more or less) undefined. What happens if I type LOAD on an USR file? The same? And what about LOAD,* ? Does it load the first PRG file or load the first <whatever> file? Sorry for not trying myself but I don't have access to my PC right now... >> I found a hint that both PRG and SEQ are limited in size, >> maybe USR not? > > I think there is no real difference in the limits. REL files have different > limits but they are generally different. I was refering to http://www.c64-wiki.com/index.php/VC-1541 which says: PRG program files (maximum filesize approximately 200 blocks) SEQ sequential files (only usable with computer applications; max. filesize 168.656 Bytes) USR user-files (special format of a sequential file) That sort of led my to the idea of different size limitations... >> All this leaves me (as a non-CBM insider) quite puzzled: If non-PRG >> files play a significant role, then why does a supposed-to-be-mature >> tool like 1541 not support them ?!? > > ? Of course it does.. ;-) > [...] > c1541 #8> write .profile profiles,s > [...] > c1541 #8> write .profile profileu,u Thank you for that information. Now I understand that the C1541 doesn't need to say something about it as it is part of the DOS command syntax - hopefully getting it right now...
