	I am trying to do set a variable that includes spaces, but the
	set deletes them.
	I type:

	$ set t="Mon   5"
	$ echo $t
	$ Mon 5

	What happens is that the set deletes the extra spaces I put 
	in the set.
	How could I preserve the spaces?

	Any help will be appreciated.

	Thanks,

	Martha DasSarma

  Wrong.  The spaces are not deleted when you do the set, they are deleted
when you do the echo, since the echo command echoes each of its arguments,
separating each of them by one space.

	% set t="Mon   5"
	% echo $t
	Mon 5
	% echo "$t"
	Mon   5

Set hasn't deleted the spaces, they were deleted in the parsing of echo, just as if
you typed $ echo Mon   5. Try $ echo "$t".
