Declaring shell variables!!

Hi All,

I want to write a shell script that can work with C-based [tcsh,csh etc]
and non C-based [bash,ksh etc] shells.
I need to declare some shell variables in this script and different
shells has different syntax to declare shell variables. So, my problem
is how to declare my variable in script so that it can run in all the
shells?

my test.sh is as follows
#!/bin/sh
abc=3D7
myname=3Dbhopal
......
....

So, now the shell script can be invoked in following manners
a)
1. chmod +x test.sh =

2. ./test.sh

or =


b)
2. /bin/tcsh test.sh

In case a) the "sh" shell will be used to execute test.sh and it will
run successfully, but if the b) method is used to run the script it will
fail.

One of the solution I can think of is to test the shell used to invoke
the script e.g.

if [invoke_shell_name contains either tcsh or csh] then
set abc=3D12
set myname=3Dbhopal
else
abc=3D12
myname=3Dbhopal
fi
...
...

So, my quesiton is can I determine the shell script used to execute my
shell script on the fly? =


I will appreciate any other approach to write a SHELL independent
script.


Thanks and Regards,
