Tom Kincaid asked about a case statement for PostScript. Sun wrote just such
a beast for NeWS. Perhaps somebody at Sun can make the decision to post it
(it is copyrighted). For anybody who might want to go out and write a case
function in PostScript, here's a syntax description of Sun's:


% A case/switch statement.  Takes a key for the case and an array.
% Generally the array is executable to avoid evaluating the array
% each time case is called:
%	obj {
%	    key1	{proc1}
%	    key2 key3	{proc2}
%	    key4	{proc3}
%	    /Default	{proc4}
%	} case


If somebody at Sun is listening, I think it would be a nice idea to post a
number of common functions defined in basics.ps, such as the rectangle and
list utilities, /case, /sprintf, and /append. I think this would help reduce
incompatible implementations of the same stuff in the future.
