Ah, ok, I remember your earlier message about the DEC indexing earlier…no, it doesn't work like that, it works like the PD program you described. BTW, in re: indexing, the way AmigaDOS does a directory is rather like that for all files. UnLike MS-DOS and lots of other DOS's, it doesn't output a linear directory listing, but rather an indexed directory listing based on a hash of the filename and lookup table. It hashes the filename, looks at the hashed value offset in the root block, then goes to the block pointed to at the offset. It reads the real filename at that block and if they match..starts the read, if it doesn't, it goes back to an extension block of the root block, and looks at that hash offset in that block, etc. I've checked quite a few disks, and only found a few disks that had 2 files that hashed to the same number and thus required the extension block lookup.
