Design things while looking at This brings to mind a question that I'm suprised that none of the hackers here have asked already: Does 2.0 support a kosher way to start a CLI process by an existing CLI application (or even WB) such that: 1) New process has a full CLI environment. 2) Parent can specify Input() and Output() of new process 3) When new process exits, its CLI quits too without reading from Input(). 4) And the new process will receive CTRL-C/CTRL-D/... signals from the parent's console. 1.3's Execute() is a kludge - it does #1 real well but no matter what I do 2, 3, or 4 gets screwed up. I can usually work around it by using hacks that I have no prayer of working in 2.0, what a bummer. (Can you say 'mucking around with struct FileHandle'? ...I knew you could). Hey, like u said, my code works, work well, but can't wait to see how miserably it fails in 2.0. I don't like doing that, mind you, but if there's a kosher way of doing this in 1.3, I'd like to know. P.S. Great job on the 3000, dudes. P.P.S. This is not a flame about 1.3 or anything. -- Rock Lobster. Honorary member of the Obfuscation Programmers' Society of America. (Membership: 1).

Well, Hackercorp finally has our beta release (yea, how's that for speed!), and I'm seriously impressed. Great stuff, Commodore. Impressive software. Now I go into waiting mode until the real thing comes out and I find out how much it's going to be to upgrade. In the meantime, expect lots of questions... There will not be any Browser 2.0. Workbench 2.0 seems to have everything I could possibly want. There might, however, be a compatibility library to add some of the 2.0 DOS calls to 1.3... you see, I had to implement quite a few of them to get Browser working. Going over my source code and the Autodocs together is sort of like deja-vu all over again (hey, Boo-Boo, where have I heard THAT one before?). -- _--_|\ Peter da Silva <peter@sugar.hackercorp.com>. / \ \_.--._/ I haven't lost my mind, it's backed up on tape somewhere! v "Have you hugged your wolf today?" `-_-'

Ok, here's one for ya. I've followed the rules with JR-Comm, but I've noticed one thing with the local dealer's A3000 that I've been sneaking on to do some testing with 2.0. With 1.2 and 1.3, I can open a window on the Workbench screen and keep the window title hidden, but on the A3000, whenever I'm using the Workbench and toggle the menu button to look at the menus I have the blank title bar remain until the screen either scrolls or I do a clear screen on it. I'm hoping this is just a bug in the current 2.0, but just checking to make sure.... -jack-

Well, here's one difference I've found on a developer-friend's 1.4beta: the ENDGADGET flag on a boolean REQGADGET is no longer sufficient to get a requester to go away. Adding another flag (e.g., RELVERIFY) makes it work. I don't know if this has been fixed in the 2.0beta, but it worked fine in 1.2 and 1.3. Lots of programs that open requesters will wait forever for a REQCLEAR message that will never come if this isn't fixed. I may get to try it on a 2.0beta later this week. Another problem with the 1.4beta has to do with MENUVERIFY and how the right button is handled. One of my programs does something, er, special, with the right button if the pointer is over a certain part of the window. It does this special thing over and over until the button is released. Under 1.4beta, it only does it once and then the menu gets activated even though I sent back MENUCANCEL to the MENUVERIFY message. Again, I hope to test this with my developer-friend's 2.0beta sometime this week. _____ | Todd M.
