standard.adl - a set of ADL definitions intended to make
ADL programs conform to the standard set in the document
"ADL Player's Handbook" by Brengle and Cunniff. standard.adl
should be portable to all ADL implementations, and should
work elegantly and efficiently, encouraging its use by programmers.
The following is the "interface" to standard.adl. It tells
