To: info-mac@SUMEX-AIM.ARPA After extensive editing of a file in MS-BASIC, I saved the file and quit. Much to my surprise, I found that my file, whose icon was still present on the screen, now occupied 0K of memory. After a little searching, I found that the System file in the System Folder was now an MS-BASIC program icon. Although GET-INFO showed that the System file occupied its usual 82K, I was able to load it into MS-BASIC, where it proved to be none other than my original file! So apparently what happened was that the System file had been destroyed and replaced with my file; the icon was updated to reflect the (inadvertant) change, but not the icon location (it was still in the System Folder), nor the icon name (it was still "System"), nor the icon size information. I managed to undo the damage by copying the System file, trashing the original and bringing over a new copy of the System from another disk. Then I loaded this (pseudo)-System file copy into MS-BASIC, making a trivial change (probably unnecessary) and saving the result under my original file name. My file now had the correct size information. Then I trashed the (pseudo) System file copy. I don't know if this is a bug in MS-BASIC or the System (I was using the latest release of the latter). I also have no idea what circumstances might have caused it. --Jeff Rosenschein -------
