Aucbvax.6856 fa.info-vax utzoo!decvax!ucbvax!info-vax Thu Apr 22 07:46:38 1982 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 """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:[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.
