Hi.

Writing it does not work does not help us help you. Post the error messages(s).

You're an old hand here, so you know that it's best to use CODE tags around code and data. You'll be inviting more responses if you do that.

Here is an example that uses underscores in names with a foreach:
Code:
#!/bin/csh

# @(#) s1       Demonstrate foreach.

# Infrastructure details, environment, commands for forum posts. 
# Uncomment export / setenv command to run script as external user.
# export PATH="/usr/local/bin:/usr/bin:/bin"
# setenv PATH "/usr/local/bin:/usr/bin:/bin"
echo
setenv LC_ALL C ; setenv LANG C
echo "Environment: LC_ALL = $LC_ALL, LANG = $LANG"
echo "(Versions displayed with local utility version)"
sh -c "version >/dev/null 2>&1" && version "=o" csh
echo

set my_list = ( the hole in the wall gang )

echo $my_list

foreach item ( $my_list )
        echo $item
end

prodiucing:
Code:
$ ./s1

Environment: LC_ALL = C, LANG = C
(Versions displayed with local utility version)
OS, ker|rel, machine: SunOS, 5.10, i86pc
csh Aug 8 2006 (SunOS 5.10)

the hole in the wall gang

As you probably have seen in your searches here at unix.com, the use of csh / tcsh for scripting is discouraged for a number of reasons. If you can, use the Bourne shell family for scripting: sh, bash, ksh, zsh.

Best wishes ... cheers, drl

NAME
echo - echo arguments to standard output SYNOPSIS
/usr/ucb/echo [-n] [argument] DESCRIPTION
echo writes its arguments, separated by BLANKs and terminated by a NEWLINE, to the standard output. echo is useful for producing diagnostics in command files and for sending known data into a pipe, and for displaying the contents of envi- ronment variables. For example, you can use echo to determine how many subdirectories below the root directory (/) is your current directory, as follows: o echo your current-working-directory's full pathname o pipe the output through tr to translate the path's embedded slash-characters into space-characters o pipe that output through wc -w for a count of the names in your path. example% /usr/bin/echo "echo $PWD | tr '/' ' ' | wc -w" See tr(1) and wc(1) for their functionality. The shells csh(1), ksh(1), and sh(1), each have an echo built-in command, which, by default, will have precedence, and will be invoked if the user calls echo without a full pathname. /usr/ucb/echo and csh's echo() have an -n option, but do not understand back-slashed escape characters. sh's echo(), ksh's echo(), and /usr/bin/echo, on the other hand, understand the black-slashed escape characters, and ksh's echo() also understands a as the audible bell character; however, these commands do not have an -n option. OPTIONS
-n Do not add the NEWLINE to the output. ATTRIBUTES
See attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Availability |SUNWscpu | +-----------------------------+-----------------------------+ SEE ALSO
csh(1), echo(1), ksh(1), sh(1), tr(1), wc(1), attributes(5) NOTES
The -n option is a transition aid for BSD applications, and may not be supported in future releases. SunOS 5.10 3 Aug 1994 echo(1B)
