find, find_equal
find, find_equal — search a list using the eq and equal functions.
Syntax
find (s_exp, list)
find_equal (s_exp, list)
Arguments
- s_exp
Any Gamma or Lisp expression.
- list
Returns
The tail of the list starting at the
matching element. If no match is found, nil.
Description

list comparing each element to the
s_exp with the function
eq. The find_equal function
uses equal instead of eq for
the comparison.
Example
Gamma> find(#a,#list(d,x,c,a,f,t,l,j));(a f t l j)
Gamma> find("hi", #list("Bob","says", "hi"));
nil
