Im working on a little low level drive access, using the exec.library SendIo routine to access the disk drive, and read a few tracks into memory.. The only problem is, when I use SendIo with my request block, I have to use WaitIO in conjunction, to make sure my program doesnt trample all over itself.. On the other hand, I could just use DoIo, but it doesnt work any better in this case either... Anyway, here's a short listing of what Im doing.. (pardon my assembly) :-) movea.l 4,a6 ;execbase lea diskio,a1 ;address of our IoRequestblock move.l #reply,14(a1) ;pointer for reply messages? clr.l d0 ;unit # (0 for df0:, 1 for df1:) clr.l d1 ;flags.. none lea tdevice,a0 ;location of text name for device jsr -444(a6) ;_LVOOpenDevice (trackdisk.device) movea.l 4,a6 ;execbase, of course lea diskio,a1 ;now, point to our IoRequestblock move #2,28(a1) ;command RW_READ move.l #4*512*11*2,36(a1) ;length of data (4 tracks) move.l #$40000,40(a1) ;buffer for data move.l #0,44(a1) ;Offset for start of read in bytes jsr -462(a6) ;_LVOSendIo (read it in!) movea.l 4,a5 ;execbase lea diskio,a1 ;pointer to request jsr -474(a6) ;_LVOWaitIo (wait for disk) movea.l 4,a6 ;execbase lea diskio,a1 ;pointer to request jsr -450(a6) ;close the trackdisk.device rts diskio ds.l 20 reply ds.l 8 tdevice dc.b 'trackdisk.device',0 cnop 0,2 Now, the problem lies that the WaitIo routine never returns.. I assume it is because the SendIo routine never completes itself.. But I cannot for the life of me find out why it wont finish.. I can even hear the disk heads step 4 times, as it is reading the data, and I can reboot the machine and look in the memory where I sent the data, and it made it through ok. But the #@!#!^ SendIo routine never finishes! What could possibly be causing this? Also, I TRIED using DoIo instead of SendIo, but the only thing that does, is the DoIo routine never finishes its task, and therefore (unlike SendIo) doesnt let me program continue..

If you can't put device names in quotation marks then how would you specify a device name with a space in it? Or, a full path name with a space somewhere in it? dh1:"bills car" No, I think the quote should be around the whole thing ... -- =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-///-= = Blair MacIntyre, bmacintyre@watcgl.{waterloo.edu, UWaterloo.ca} \\\/// = = now appearing at the Computer Graphics Lab, U of Waterloo! \XX/ = = "Don't be mean ... remember, no matter where you go, there you are."

Well, if you don't interpret things in quotes, how do you do something like "CON:0/0/640/200/CLI Window"? You need the quotes so you can include spaces in the window title, but now you're saying that this should be treated as a normal file, relative to the current directory? You can't have it both ways! I think the present situation is fine. I'm still curious as to how the original poster got a colon in the filename though - I've tried various combinations using the device name with no success. On the subject of devices, is anyone working on a ZOO: device which would let you CD to a Zoo Archive, DIR the contents and then read or execute various files within it just as if they were uncompressed. Writing wouldn't need to be implemented, only retrieval. I'd find this really useful. Of course, you'd need to allow colons to appear more than once in a device name for this to work (DIR ZOO:DF0:FRED.ZOO) :-) Eddy -- Eddy Carroll ----* Genuine MUD Wizard | "You haven't lived until INTER: ecarroll@cs.tcd.ie | until you've died in UUCP: {..uunet}!mcvax!ukc!cs.tcd.ie!csvax1!ecarroll | MUD!" - Richard Bartle

In-Reply-To: message from bleys@tronsbox.xei.com That's interesting, since most of the really neat demos I've seen lately are from Europe, they're in PAL, so the scroll messages can't be seen on my 1084 at home. I have to run them on the A3000 at work in PAL mode...

While I know this may not be a bright question, and has probubly been discussed before (refering to CPUSpeed), here goes... What effects/performance increases will/should be apparent by adding the line: CPU Burst to the startup-sequence on my A3000/25? What aspect of performance does this affect? I know it turns both DATA and INSTRUCTION caches on, but what exactly will these affect in my every-day computing (telecommunications, 3D renderings, DPaint animating, etc.)? I hate asking questions that should seem obvious, but I was asked myself, and I didn't have a good answer...TIA Sean //////////////////////////////////////////////////////////////////////////// UUCP: ...!crash!pnet01!pro-party!seanc | ARPA: !crash!pnet01!pro-party!seanc@nosc.mil | " Fanatics have their INET: seanc@pro-party.cts.com | dreams, wherewith they | weave a paradise for RealWorld: Sean Cunningham | a sect.

In-Reply-To: message from chrisw@gondor.actrix.gen.nz I have also been searching for an Amiga program to replace the IBM PC programs Derive and Eureka. The best thing seems to be Mapple which blows them both away and is also available for many platfroms including the Amiga. I was in the dentists office last week and I picked up a copy of Discover (a scientific magazine), and Mapple was rated the math package breakthrough in scientific technology. Mapple costs $400 for the Amiga and is availble from Waterloo Software in Canada. ------------------------------------------------------------------------- ProLine: danb20@pro-graphics *************************** UUCP: ...crash!pro-graphics!danb20 * Dan Bachmann * ARPA/DDN: pro-graphics!danb20@nosc.mil * Raritan Valley College * Internet: danb20@pro-graphics.cts.com *************************** P-Link: DanB20 <-- I only read PLink once a mo. use Internet U.S.Mail: 509 StonyBrook Drive, Bridgewater, NJ 08807
