set LD_LIBRARY_PATH=${MY_TOOLBOX}/lib
set path=($path /usr/bin/ttx /usr/bin/ttx/FreeBSD ${GGSN_TOOLBOX}/bin)

It is following csh syntax of env vars (set ENV=soemthing)

My problem is when I source the above modified .cshrc, I get an error that is complaining on the "(" in the path variable..

Am I not following the right syntax for the path variable?

Thank you very much for your patient replies. Much appreciated.

This is because there is already an existing bourne script and I need to add the support to modify the cshrc...

Sorry for double posts..

You cannot do this between BOURNE and csh - they're totally different with different syntax - they don't mix (in simple terms).

env

ENV(1)							    BSD General Commands Manual 						    ENV(1)

NAME

     env -- set and print environment

SYNOPSIS

     env [-i] [name=value ...] [utility [argument ...]]

DESCRIPTION

     env executes utility after modifying the environment as specified on the command line.  The option name=value specifies an environmental
     variable, name, with a value of value.  The option '-i' causes env to completely ignore the environment it inherits.

     If no utility is specified, env prints out the names and values of the variables in the environment, with one name=value pair per line.

DIAGNOSTICS

     If the utility is invoked, the exit status of env shall be the exit status of utility; otherwise, the env utility exits with one of the fol-
     lowing values:

     0	     The env utility completed successfully

     1-125   An error occurred in the env utility.

     126     The utility specified by utility was found, but could not be invoked.

     127     The utility specified by utility could not be found.

COMPATIBILITY

     The historic - option has been deprecated but is still supported in this implementation.

SEE ALSO

     execvp(3), environ(7)

STANDARDS

     The env utility conforms to IEEE Std 1003.2-1992 (``POSIX.2'').

BUGS

     env doesn't handle commands with equal (``='') signs in their names, for obvious reasons.
