I did not use the "CORE::" prefix when I tested. I too get your results when I do. In any case the main point still holds: both map and sort according to your machine (and mine) have an undefined prototype. The fact of an undefined prototype does not provide an explanation of the different behavior. I only wish it were that simple. But thanks, anyway, for your help. Best, beth	[reply]

`sort` actually calls a sub. In fact, you can actually pass a sub name. `map` is like `while`. No subs are involved.	[reply] [d/l] [select]
