Dennis:
	I did a similar thing for a customized 'su' program.  This new
'su' program not only changed existing shell variables but added new ones
as well before exec'ing the shell.

	What I did was to steal that part of the code that creates shell
variables from the 'csh' source code.  If you don't have access to source
code then I would suggest learning how to manipulate the 'environ' variable
which is defined as 'extern char **environ'.  The documentation should
explain how to at least get access to environmental variables and should
get you on your way.
