Re: Learning about GLOBALS late in life . . .
Richmond If the globals are defined in a handler, they must be defined in each handler using them... if you define them at the script level, no problem Jacques Le 16 nov. 2009 à 17:53, Richmond Mathewson a écrit : tried this: on mouseDown global LEFTT, TOPP put the top of fld acre into TOPP put the left of fld acre into LEFTT grab me end mouseDown on mouseUp put the bottom of fld acre into DOWP put the right of fld acre into RITE put RITE - LEFTT into WIDD put DOWP - TOPP into HITE end mouseUp and the third line within the 'on mouseUp' threw a bluey ?? ___ use-revolution mailing list use-revolution@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-revolution ** Prof. Jacques Hausser Department of Ecology and Evolution Biophore / Sorge University of Lausanne CH 1015 Lausanne please use my private address: 6 route de Burtigny CH-1269 Bassins tel/fax:++ 41 22 366 19 40 mobile: ++ 41 79 757 05 24 E-Mail: jacques.haus...@unil.ch *** ___ use-revolution mailing list use-revolution@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-revolution

Actually, Colin, your advice about globals was more correct insofar as it answered my question, but Mark's was pedagogically more useful as I had 'forgotten' about locals [ the truth of it is that ever since I discovered Hypercard and escaped from the joys of variable declaration (think BASIC, FORTRAN, PASCAL) I was unaware (or unwilling to think about the fact) that variables could be declared in xTalk languages. Today, mucking around with something that had to stay there between 2 handlers a little bird at the back of my head started tweeting 'global' - it didn't tweet 'local'] Big Thanks to both of you. ___ use-revolution mailing list use-revolution@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-revolution

Interestingly, I knew the answer not from knowing Rev, and certainly not HyperCard (which doesn't work that way with variables), but from Lingo. In Director you can do the same kind of thing, both with global variables and with property variables. ___ use-revolution mailing list use-revolution@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-revolution
