You can elect to use an alternate editor by specifying the editor with the MTEXTED
system variable.

If you use an alternate text editor for multiline text, you specify the properties
of the multiline text object at the Command prompt first. Then the text editor opens
for entering text. When you close the text editor, the text is inserted within the
width limit you specified.

If you use an alternate editor, you must enter special codes to apply formatting.

To edit text using an alternate text editor, use the same format codes. To avoid losing
format information when you make changes to the text, use the same text editor you
used to create the text.
