pack .lMichael Jacobson: Also see Comic Server for some code to get a bunch of comic strips from uComics. Or you can check out (on windows only ~ sorry) in a TclKit application that servers the comics and display them in a embededd MSIE frame using optcl. Get the application here ... http://mywebpages.comcast.net/jakeforce/COMon!ics.kit (96kb). (I use this code in NewzPoint)
02. Aug. 2005: The Text for the daily gilbert comic changed. Replace the lsearch line with the following:
