ENV vars in SED patterns

In a csh script, I want to use 'sed' to substitute a placeholder pattern with user's full names (extracted from GCOS with a targeted grep/cut operation and set to variable $NAME).
The script line I have goes like this:
         sed -e 's/PUTNAME/'$NAME'/' < $LOC/.vacation.msg1 > $LOC/.vacation.msg
Problem is: 'sed' doesn't  like the space between first and last name:
         sed: command garbled: s/PUTNAME/Cal
(note how it drops my last name)
Can someone suggest a better sed string and comment on quoting variables in 'sed'?

Hi...
Take out the single quotes around $NAME or change them for double quotes ...
sed -e 's/PUTNAME/"$NAME"/'

The single quote is understood by sed to mean start and end of the editor commands.
That is why you get the garbled message. If you want to quote variables in sed then double quote them.

Sorry.

The double quotes make the strings enclosed literal.

I'm editing a generic vacation notifier message header and get:

From: "$LOGNAME"@eciad.bc.ca ("$NAME")

So now it's literal AND I get doublequotes around the quoted vars!

sed -e "s/PUTNAME/$NAME/" < $LOC/.vacation.msg1 > $LOC/.vacation.msg
sed -e s/PUTNAME/"$NAME"/ < $LOC/.vacation.msg1 > $LOC/.vacation.msg

It's not really sed who's processing the " or ' or space here.
They were being parsed by csh to determine what to pass to sed.

I take it you've gotten the answer you wanted?
sed -e "s/PUTNAME/$NAME/" < $LOC/.vacation.msg1 > $LOC/.vacation.msg
