122 The NED ASCII Text Editor
MX3 Reference Guide E-EQ-MX3RG-J-ARC
The NED ASCII Text Editor
NED uses the standard Microsoft Windows interface for cut, copy, and paste operations. Del and
Shift+Del both move the selected block to the clipboard. There is no true undo command, but
Ctrl+V or Shift+Ins may be used to paste the clipboard contents to the current cursor position.
Table 1 lists all the default shortcut keys.
The NED editor is a menu-based text editor available for use with ROM-DOS. This editor is
similar to other desktop editors but has special functions designed for use in editing C-source and
assembly code.
To start the editor, enter
NED [filename] [filename]
NED may be initiated with or without filename arguments. Wildcard file specifications are
allowed.
Up to ten files can be entered on the command line. If NED is run without arguments, it loads all
files accessed during the last editing session, returning you to the exact position in the file. You
can switch between the open files.
You can also enter
NED @errfile
where errfile is the name of your compiler error output file. NED loads all files that had errors and
allows you to move between errors.
Once NED is running, you may load files into memory by using the File/Open menu command.
File/Reload replaces the current file with a new file or reloads a new copy of the same file.
File/Reload confirms before replacing an unsaved file.
• If a search string is all lowercase, NED treats it as a case-insensitive search. If a search
string contains any uppercase letters, it is case sensitive. The replacement string is
inserted exactly as entered. Repeating a Search command repeats the last Forward or
Backward Search operation, not the last Replace operation.
• There is one bookmark for all files. Once the bookmark is set, going to the bookmark
returns you to the file and position where you set it.
• The Indent and Remove-indent (referred to as Undent in the Options/Do Command)
commands work on tabs. Indent inserts a tab at the beginning of the current line, or if a
block is active, at the beginning of each line in the block. Remove-indent removes the
first tab from the current line or from each line in the block. If there are no tabs, Remove-
indent has no effect.
• Toggle case inverts the case of the current character if no block is active. If a block is
active, Toggle case sets the entire block to uppercase if the first character was lower and
to lowercase if the first character was uppercase.
• Tabs are currently set to 3 for .C, .H, .CPP, .HPP, and .T files. They are set to 8 for all
other files.
• File/Print prints the current block if there is one, otherwise it prints the current file. NED
prompts for a device to print to, which may be a filename. Tabs are expanded to spaces.
• The Options/Do Command is intended primarily for debugging. This command allows
you to execute any editor command by choosing it from a menu list.
