I typed in the program below from an atari programming book (Understanding Atari Graphics) and I'm getting an error 5 in line 290 and can't figure out why. I don't think I made any mistakes. (checked it a bunch of times). Any suggestions?

Does anybody know about these new xe/xl power supplies that are on eBay? Are they any good? Any advantage to them?

UGGG!!!

I just spent the last two weeks typing in some programs with my 130XE w/Spartados 4.45 w/the IDE plus adapter.

Now I got a (I think) error 181 directory corrupt error and my directories list garbage. Am I screwed? Any suggestions?

I'm having a problem with the SORTDIR command in Spartados 4.44.

I was typing in some programs from a book and saving the files. I sorted them a couple of times as I added more programs to the folder with no problems. After I got to a couple of pages of programs (about 50 or 60 programs I think) they stopped sorting. I am up to 70-80 programs and it still won't sort them anymore. I moved them all to a new folder and tried it again but no nothing changed.

Any suggestions?

Can I use my SDrive Nuxx and 1050 drive together by plugging the SDdrive into the 1050 and then the 1050 into the computer? Will this damage anything?
