You are already trying to use bourne shell! $() is bourne syntax. You only get to use `` in csh.

csh can't do the kind of doublethink where you put a csh statement in a variable then execute it, either. sh can, but you have to force it, since it's very seldom a good idea to do so.

This will get them in an array where each number is its own index:

Code:
set VAR = ( `tr -d ",()'" < infile` )

...which you can then process with a loop to get the numbers three to an index like you want.

use

USE(1)								   User Commands							    USE(1)

NAME

       use - Frontend to the Usepackage Environment Manager

SYNOPSIS

       csh and derivatives:
	       source /usr/share/usepackage/use.csh

       bourne shell and derivatives:
	       source /usr/share/usepackage/use.bsh

       korn shell:
	       . /usr/share/usepackage/use.ksh

       use [-vs] [-f file] package ...

       use -l

DESCRIPTION

       Usepackage  is an environment management program. It is based on the principle of packages - collections of executables that share a common
       set of necessary environment variables, such as PATH, MANPATH or LD_LIBRARY_PATH.

       For each given package, use sources the appropriate environment information into the current shell.  The environment information is  speci-
       fied in a configuration file, see usepackage(1).

   OPTIONS
       -v     Output verbose information to the standard error stream.

       -s     Silence  warnings  for  un-matched  packages. This is useful in a shell rc script when a package is known not to be available on all
	      architectures that the shell is used on.

       -f file
	      Specify an alternate initial configuration file.

       -l     List available packages and groups.

FILES

       /usr/share/usepackage/usepackage.conf
		      The default configuration file.

       /usr/share/usepackage/use.csh
		      Shell setup for csh and derivatives.

       /usr/share/usepackage/use.bsh
		      Shell setup for bourne shell and derivatives.

       /usr/share/usepackage/use.ksh
		      Shell setup for ksh.

       /usr/bin/usepackage
		      The underlying Usepackage executable.

ENVIRONMENT

       Other than the reading and re-definition of environment variables for package setup, use also uses the following environment variables  for
       user configuration:

       PACKAGES_PATH  Colon-separated  path  list  giving  the directories to search for configuration files. Shell-style tilde (~) user-directory
		      escapes are expanded.

       HOME	      If present in the environment, this is used to provide the expansion for the tilde (~) user-directory.

       SHELL	      If present in the environment, the last path component of this is used for shell matching (see  SYNTAX)  and  detecting  the
		      style of environment output that should be used, see usepackage(1).
