If you can't afford to buy FMS or TDMS, you know how frustrating modifying 
long Datatrieve fields can be.  This program can be installed "into" the 
datatrieve image to give a crude but effective editing capability.  It 
requires VT100 or compatible terminals (see comments in code for what features
are used) and is most effective used from procedures, thus:


		DTR> NAME=FN$STR_EDIT(NAME)

		DTR> READY PERSONNEL MODIFY
		DTR> FIND PERSONNEL WITH LAST_NAME="SMITH"
		DTR> SELECT
		DTR> MODIFY USING ADDRESS=FN$STR_EDIT(ADDRESS)

 Editing keystrokes are the same as for VMS line recall editing, with one
 extension; CNTRL/W for advancing one word.


I have included a help file.  Use LIBRARY/CREATE/HELP to put it together and 
assign the logical name HELP$LIBRARY (or HELP$LIBRARY_1, HELP$LIBRARY_2, or 
whatever your system is not using) to it so that help will be available from 
datatrieve.

Comments, questions, improvements should be sent to :

** NOTE **

	There is one outstanding bug.  With a large field (234 characters at 
last try), put the cursor at the last position then hit backspace (^H) to go 
to beginning of line.  >CRASH!<  I haven't got around to looking for this one, 
yet.
