I am trying to write a very simple little program that will search a record
and give me a result of true if the word is in the record, false if it
isn't.
as an example...
Lex=lex(1:X1 2:X2 3:X3 4:X4)
declare
fun {IsItThere W}
if Lex.W \=nil then true
else
false
end
end
Firstly it doesn't work right, and I think I have the semantics wrong for
using a record. If it were a list i would use the case statement and pull
the head off compare them, and repeat it until the list was nil. But for a
record to see if it is in there at all, you just have to {Browse Lex.W} and
it would come up with the result if it is there or an error if it isn't.
Can I make this a boolean function easily?
