Jerry Leichter's comment about being able to tell by looking at reference to a name whether its value may be implicitly or directly changed seems to have a hole in it. If I pass an array to a function by specifying the array name, a pointer to the array is passed, thus making it possible for the function to change the contents of the array. However, I have to remember that the object was declared as an array to realize this. It isn't explicit in the call syntax. -- David Dyer-Bennet -- {ihnp4|decvax|ucbvax|...}!decwrl!rhea!mrvax!ddb
