DED Disk Editor ded pathlist dEd is a screen-oriented disk editor utility. It was originally conceived as a floppy disk editor, so the display is organized around individual sectors. It performs most of the functions of Patch, from Computerware, but is faster, more compact, and screen-oriented rather than line-oriented. Individual files or the disk itself (hard, floppy, ram) can be examined and changed, sectors can be written to an output file, and executable modules can be located, linked to and verified. With simple changes, it will run on any CoCo Level I OS-9 and possibly others (CoCo Level II OS-9). To use, type: dEd pathlist where <pathlist> is of the form: filename or dirname or /path/filename or /D0@ (edits entire disk) dEd will read in and display the first 256 bytes in the file (disk). This is Logical Sector Number (LSN) zero. You move through the file sector (LSN) by sector using the up and down arrow keys. The current LSN number is displayed in Hex and Decimal in the upper left corner of the screen. If the disk itself was accessed (by appending '@' to it's name when dEd was called), the LSN is the disk sector number. If an individual file is being editted, however, the LSN displayed refers to the file, not to the disk. All numbers requested by dEd must be in Hex format. All commands are accessed by simply pressing the desired key.
