I was talking specifically about array of const, not Pascal in general. The docs do not make it clear that array of const can accept different types in "one call". We are talking purely about "array of const" here, not the Pascal language in general. Of course I know the Pascal language can accept multiple types in one call. > > > But in fact, with array of const, you can use multiple types. > > You can, just as you can use different types in record types. > Still, the actual argument type would be the type of the record or, as in > your case "array of const" then. Don't confuse that. Well you are nitpicking my email :-). I'm not confused at all - the docs are. All I was asking was why specifically in array of const's case, the docs did not make it clear I could pass multiple types in the same call. If you look in the examples in the docs page, all the examples show the programmer passing arguments of the same type in one call. They only make it clear that you can pass multiple types in separate calls, not in the same call. // passing multiple types, but in separate calls test([TRUE, FALSE, TRUE]); test(['string1', 'string2', 'string3']); // passing MULTIPLE TYPES IN ONE CALL, not stated anywhere in docs test([TRUE, 'string1', 342, -456, 1.653]); > > And you still can't just pass two arguments when the subroutine expects > only one Isn't this exactly what array of const is for? It allows you to use anywhere from 1 to unlimited parameters. _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
