Under tcsh, when i run "ctest /var" through the following alias,

alias ctest 'echo $1; pushd $1'

The screen looks like this:
> ctest /var

/var ~


If I try this one:

alias ctest3 'pushd $1; echo $1'

>ctest3 /var
pushd: No other directory.

could anybody tell me why the $1 system fails in alias? If I type the above
command by:

echo /var; pushd /var

or

pushd /var; echo /var

they both work.

That is not the correct syntax for alias parameters under csh/tcsh.

To reference the first parameter you need

alias ctest 'echo \!:1; pushd \!:1'

Obviously the second parameter will be \!:2, etc, etc,
and all parameters is \!:*

You should review the manual page for tcsh since pushd is a built in
under tcsh and has some behavior specific to tcsh, along with some
special variables

See especially

QUOTE
Directory stack substitution (+)
The directory stack is a list of directories, numbered from zero,
used by the pushd, popd and dirs builtin commands (q.v.).
dirs can print, store in a file, restore and clear the
directory stack at any time, and the savedirs and dirsfile
shell variables can be set to store the directory stack
automatically on logout and restore it on login. The
dirstack shell variable can be examined to see the directory
stack and set to put arbitrary directories into the directory
stack.
