	Fellow TECO users,

Wow!  Nice to see I'm not the only one left!
	
	We're on VMS 4.5 and have just migrated from a VAX 11/780
	with RM05 disks to a VAX 8250 with RA60 (system) and RA81
	(user) disks.

	...$EDIT/TECO no longer works and gives the  following ERROR message:

%LIB-E-ACTIMAGE, error activating image DJA0:[SYS0.][SYSLIB]CEM$EMULATOR.EXE;
-RMS-E-FNF, file not found

	(were DJA0: is the NEW system disk device name)

	...

TECO V40, which is what you get with VMS V4.5, is a curiosity, an image that
runs half in native mode, half in compatibility (PDP-11) mode.  (Basically,
the TECO interpreter runs in compatibility mode - it's the same code that
runs on -11's.  The I/O system, which comes in different flavors on -11's to
deal with different OS's, on VMS switches back to native mode.)

The VAX 8000 series does not support compatibility mode in hardware.  Hence,
TECO would normally not work at all - in fact, Version 39 could not be made
to work.  Version 40, on the other hand, has the hooks necessary to run under
the PDP-11 instruction set emulator - CEM$EMULATOR.  CEM$EMULATOR does not
ship with VMS - it's part of the VAX-11 RSX layered product.

It was announced at the last DECUS that Version 5 of VMS would ship with a
new, all-native TECO.  If you can wait 'till then....
