     MS-DOS 5.0 Editor emulation for the Borland/Turbo Pascal IDE.

	This file contains a Turbo Editor Macro Language (TEML)
script which emulates the MS-DOS Editor in the Borland/Turbo Pascal IDE.
A complete description of the TEML language and the Turbo Editor Macro 
Compiler (TEMC) can be found in the file "TEMC.DOC".

	The TEMC compiler can be invoked from the DOS command line as
follows:
 
	  temc [-c] dosedit.tem <IDE configuration file><.CMD><.TP>

The optional -c switch can also be specified as /c, and can appear in
any argument position on the command line. If you use this option,
any existing command table in your configuration file is thrown away
before the script file is merged with those already defined. The
configuration file extension must be specified as TEMC will modify both DOS
and Windows IDEs config files.  Specify .CMD or .TP extentions for Windows
or DOS IDE, respectively. If the .CMD file does not exist, it will be 
created. The .TP file must exist, or an error is displayed.

Most of the simple editor commands have been fully implemented.  Most
of the complex commands have been either partially implemented or not
implemented at all. Below is a list of the commands that have been
fully or partially implemented.
