Reserved to customer ECO numbers?
>From EPS@MIT-AI Thu Apr 22 07:38:50 1982
Do any of you know which ECO numbers are reserved for customer
use?  The PATCH manual doesn't say, but LIB.REQ seems to imply
that the fourth ECO longword is.  LIB.REQ also says that 99(!)
ECO numbers are crammed into 96 bits, and 132(!!) into 128.  I
don't believe it.  In any case, are there reserved-to-customer
ECOs, and if so, do they start at 97, 99, 100, or 101?

				One very confoosed EPS

P.S.  The reason I'm asking is 'cuz I'm putting together a set
of patches to make VMS more reasonable (please no mail on THAT
subject!).  Example:

I don't like having .LIS be the default extension for TYPE and
PRINT commands.

$!Patch TYPE to use null default extension instead of '.LIS'
$ PATCH TYPE
CHECK NOT ECO 1
REPLACE/BYTE 0BBD
04
EXIT
00
EXIT
UPDATE
EXIT
$!Similarly for PRINT command
$ PATCH SUBMIT
CHECK ECO 1
CHECK NOT ECO 2
REPLACE/INST 0C14
'MOVL #53494C2E,W^384'
EXIT
'CLRB W^279'
EXIT
UPDATE
EXIT
$ MCR INSTALL
SUBMIT/REPLACE
$ WRITE SYS$OUTPUT """Done"

I have quite a few patches that I think make the system more
pleasant to use.  Most are about this level of complexity.
I would like to put SET ECOs after the CHECK NOT ECOs.

About this particular patch (TYPE), I've been told that certain
DEC-supplied .COM files assume .LIS defaulting (e.g. UETP), so
beware if you plan on replacing the files in [SYSEXE].  In any
case you should keep the originals around.  You can always put
the revised .EXE files on a [PUBLIC] directory (or equivalent)
and users who don't like DEC's default can type
	$ ASSIGN SYS$SYSDISK:[PUBLIC]TYPE TYPE
so the TYPE command will have the desired effect.  SUBMIT is
installed with TMPMBX; all users should have this privilege
anyway so there shouldn't be any problems with using a user-
provided (i.e. not INSTALLed) SUBMIT.
