csh/tcsh problem with "Directory stack no so deep" --- related to "="

[Kin Yip]

Hello,

I have found that "csh/tcsh" (in my Linux , a few versions) has a problem
with "=" followed by a no. and with "grep" command.

Say, if I have a file temp.1  with the following line :

        1tally  25        nps =1

Then, if I do

     set tally = ` grep nps temp.1`

(back quotewould give you  the error message :

    Directory stack not that deep.


If I just give a space between "=" and "1", I won't have this problem.
And of course,  
                                  grep nps temp.1

would work too.

I have been using that "set tally = ...." for a long time without problem.
But now, the problem occurs when one count (nps) is so big such that
there is no more space after "=".

Could you please take a look ?   I could provide more information if you 
want.
