I have System V Release 2.2 on 3B2's and have used the index(3F) function
in Fortran applications.  The function is called from a Fortran program and
returns the location (i.e., integer character count) of the substring <cs2>
in the character string <cs1>.  It works like this:

	integer i
	character*len1 cs1
	character*len2 cs2

	i=index(cs1,cs2)

Index is similar to the C language function 'strspn'.
	
I am not a BSD person, so I can't tell you if BSD does anything different
from the above.
