\ TOPEDIT.SEQ   Memory edit.                            By Tom Zimmer

  Memory edit, allows reentering the editor without having to re-read
the edit file from disk. This results in a much faster turn around time
for development.  Changes made during an edit will still be saved at
the end of each edit session.

memfile         ( --- handle )
        Return the handle address of the current file in editor memory.

?readfile       ( --- )
        Load the currently open file into the editor if it is not already
        loaded. Initialize the editor.

cold-edinit     ( --- )
        Initialize the editor to no file open. Done at cold start time.

<ed>            ( --- )
        Re-Enter the editor on the current file at the most recent
        edit line. Reads the file into memory if needed.

ed              ( --- )
        Enter the editor on the most recent edit line.

edit            ( n1 --- )
        Enter the editor on the current file at line n1.

fix             ( t1 --- )
        Open the source file for the word t1, and enter the editor
        on the first line of its definition.

sed             ( | filename --- )
        Start the editor on the filename specified, or if no name
        is specified, then prompt for a file. Will create a file
        if it does not already exist.

listing         ( --- )
        Print a formatted listing of the file currently open.
