*	Messages common to more than one SCCS command.
*
-1
"unknown key letter"
You supplied a keyletter which the command does not recognize.
-2
"key letter twice"
You supplied a keyletter more than once.
-3
"missing file arg"
You left off the name of the file to be processed.
-4
"cannot create lock file"
Someone else is updating the SCCS file
(or the p-file).
You'll have to wait until they're through,
and try again.

If this persists contact your source code administrator;
your local SCCS support personnel would like to know about this
so that future occurrences will be more unlikely.
-5
"bad date/time"
The date/time must be a legitimate date/time in the form
"YY[MM[DD[HH[MM[SS]]]]]".  The program knows about things
like leap years, so be precise.
-6
"no id keywords"
No SCCS identification keywords were substituted for (or found).
If this message came from delta then you just tryed to make a
delta without any keywords.

If this message came from get then
your source code administrator blew it.
Complain to him/her.

If this message came from admin,
you blew it.
-7
"No id keywords"
No SCCS identification keywords were substituted for.
You may not have any keywords in the file,
in which case you can ignore this warning.
If this message came from delta then you just made a
delta without any keywords.
If this message came from get then
the last time you made a delta you changed the lines
on which they appeared.
It's a little late to be
telling you that you messed up the last time you made a delta, but this is
the best we can do for now, and it's better than nothing.

This isn't an error, only a warning.
-7
"value after ... arg"
You had something after the indicated keyletter argument and you weren't
supposed to.
