Re: [Ql-Users] Stupid AND
Hi, FALSE AND ERROR is FALSE ? That cannot be ! I disagree. FALSE AND ... whatever is FALSE since whatever is never evaluated. FALSE AND ERROR has to be ERROR !!! Definitely not. The first condition (a<>0) is NOT met and so, in any other programming language I use, the second condition isn't even tested, as the result will be "false" anyway because of this. So you will ever get big BIG ERRORs... I'm not sure I understand. The above example makes sure that the error doesn't even happen which is the whole reason to write it like that. SBASIC is better ;-)) In this instance, not to my mind. :-( Wolfgang ___ QL-Users Mailing List

Because there is no order for evaluating the first and the second condition in the AND operation, In any way both have to be without any errors. FALSE AND ERROR is FALSE ? That cannot be !

My systems use 7.65 without problems, which was the first high colour version. 7.66 has at least the extension problems that I noticed, too. I'm not up-to-date what changed in v8. I'll try to get the sources (and manual), maybe we can address some of the problems. Marcel ___ QL-Users Mailing List

Op Thu, 21 Sep 2017 11:00:45 +0200 schreef Giorgio Garabello via Ql-Users : 7.64 support GD2? No, this was the last mode 4 version. v7.65 is the first attempt at GD2 compatibility. IN v8.xx the Long Words that hold the palette parameter in the low bytes, also use the high bytes for extra options like timeout. This should not be a problem when used from S*Basic but may be an issue when called from machine code when the high bytes are taken for granted. This could be why in QDT LSEL does not work properly.

In my experience, the only valid QMenu version is 7.64. v8.00 got several annoyances and compatibility issues and, IIRC (that was many years ago), removed things from its configuration that broke the way I always used QMenu, so I rejected it years ago, and religiously (for an atheist, that's quite a superlative !) kept v7.64 on all my systems.

Re: [Ql-Users] QMenu v8
yes, but probably is a QDT problem.. QMenu 7.66 has a lot of problem, ink color in view_file remains always black, extension filter don't work and some other problems... Qmenu 8, works well.. maybe in QDT the author has done some "tricks" . Probably the author had to make some adjustments to make it work, which pggi annoy version 8.
