Variables in HERE DOCUMENT

Here is my problem: can we set the variables in the HERE DOCUMENT? I have tried but failed. Any one has good comments please let me know.

Code:
#!/bin/csh -f

pbrun -u xmgbrk runshell <<!
@ $num1 = `wc -l /home/tpltp/csh/scripts/who.csh`
echo "$num1"
if ( $num1 > 0 ) then
  echo $num1 | tee -a /tmp/file.$$
endif

exit
!
echo "out of csh"
exit(0)

The output will be "@: Variable name must begin with a letter."

PS: I will have no chance to input the password for xmgbrk. this is also a problem.

NAME
resize - set TERMCAP and terminal settings to current xterm window size SYNOPSIS
resize [-u] [-c] [-s[row col]] OPTIONS
The following options may be used with resize: This option indicates that Bourne shell commands should be generated even if the user's cur- rent shell is not /bin/sh. This option indicates that C shell commands should be generated even if the user's current shell is not /bin/csh. This option indicates that Sun console escape sequences will be used instead of the special xterm escape code. If rows and col- umns are given, resize will ask the xterm to resize itself. However, the window manager may choose to disallow the change. DESCRIPTION
The resize command prints a shell command for setting the TERM and TERMCAP environment variables to indicate the current size of xterm win- dow from which the command is run. For this output to take effect, resize must either be evaluated as part of the command line (usually done with a shell alias or function) or else redirected to a file which can then be read in. From the C shell (usually known as /bin/csh), the following alias could be defined in the user's % alias rs 'set noglob; eval `resize`' After resizing the window, the user would type: % rs Users of versions of the Bourne shell (usually known as /bin/sh) that do not have command functions will need to send the output to a tem- porary file and the read it back in with the "." command: $ resize > /tmp/out $ . /tmp/out FILES
for the base termcap entry to modify. user's alias for the command. BUGS
The -u or -c must appear to the left of -s if both are specified. SEE ALSO
