Alright, thank you to everyone who tested and gave advice. whichMacPerl is now updated to take embedded libraries in Mac OS 8 into account, and to tell the user certain libraries are needed for PPC Macs. http://pudge.net/macperl/wmp.html (The URL is correct this time!) For those who do not know: this is a runtime app (or text script) that tells you what version of MacPerl you should install on a given Mac. I think it is all correct, but someone let me know if it does not work right. -- Chris Nandor pudge@pobox.com http://pudge.net/ %PGPKey=('B76E72AD',[1024,'0824 090B CE73 CA10 1FF7 7F13 8180 B6B6']) #== MacPerl: Power and Ease ==# #== Publishing Date: Early 1998. http://www.ptf.com/macperl/ ==#
