signature of the Bourne shell and the C shell

[Xiang-Min Wang]

I am writing a shell script in which I want, among other things, to have
the capability of testing first the system is the Bourne shell or the C
shell. Right now, I am using some system shell variables to do that. I
do not feel comfortable with this solution. I want to know you (the
netter) have any rebust solution to this problem (test is it the Bourne
or C shell?). Any suggestions or ideas welcome. Thank you in advance.
