(LC Builder 'contains' vs 'is in') ================================= TMHO this abstract writing of Ali's examples is easy to remember, the different "level" of the comparison is visible by the brackets.
x "is in" A if and only if A "contains" [x]. (x "is in" A and y "is in" A) if and only if A contains [x,y]. etc. where A is a list, x,y is any. >> Definitions. Let A and B be lists. >> x "is in" A if and only if x is an element of A. >> B "contains" A if and only if every element of A "is in" B. _______________________________________________ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode
