MEMEDIT.HLP Mike's Memory editor for F-PC 3.35
Mike Mayo 9/13/89
This memory editor uses a dump utility, typically the standard DUMP, but
optionally using a DUMPC@ other than standard. Cursor keys move the cursor
around the screen over the DUMP'ed data to select an address to edit. You
must then press <enter> to bring up an editing line for the selected
location.
These deferred words allow the editor to be patched e.g. for editing
memory in some target processor's environment.
