Shraddhan… Unfortunately when WRITE returns a DISK_FULL error its after it has already written it, no pre-planning involved . Even the internal pointers are cleared out, so I can't even tell WHERE in the file it stopped. I'll find something out though . Thanks… David
Shraddhan… The packet ACTION_READ_RETURN is 1001, I found it in the 1.3 Includes & AutoDocs. So if I muddle around with it I might come up with something..HA . I thought about keeping a running total but the WRITE DOS call will still return -1 when the disk is full.…
AmigaDOS Question
Message #25717
Hi there… Is there any way to find out how much data has been written to disk when the DISK_FULL error occurs? I'm using 1.3 and I was thinking that the packet ACTION_READ_RETURN/WRITE_RETURN might tell me the actual number, not just -1. Thanks a bunch… David
Hey Andy… Thanks much!!! Now I have one less problem in my life David
2.0/1.3 device probs
Message #25544
Hello… I've come across some differences in 1.3 and 2.0's console.devices. Whats happening is that, in 2.0, when the cursor is at the bottom of the window and it receives a CR/LF which scrolls up the text, it fills in the bottom line with black spaces. It uses the colors…
Steve… So is it impossible to determine the beam position in an interlace mode? I would double buffer the screen, but I really didn't want to eat up all that memory. David
#Interlace problem
Message #18392
Hello… This is a simple question, but through my lack of patience I've decided enough is enough . I'm having problems reading the Vertical beam position while in interlace mode, and blittering a 4 bitplane image. It seems to me that I could wait till the beam was at the…
Allen… I believe that Amiga.lib has a "C" type routine/function that you are looking for. Its called GetChar(). It uses StdIn (like the CLI window when first booted up). I'm not sure about the specific values that get passed to GetChar(), or if it returns with D0 containing the character…
Sorry David, I don't. But I just have to ask … WHAT KIND OF USER ID IS THAT THAT YOU'RE WEARING????? Just asking… David
System Requester HELP
Message #88665
Ello… In my program I'm writing/reading to the disk, but on occassions when there is no disk in the drive, I will get the system requester that says to "Insert" So-and-so disk. This is no problem but the requester keeps popping up in the CLI window and NOT my screen.…
Ed… Thanks alot….now I only have 10,050 questions left . David

#What is with Lock()?
Message #88342
Ello again… Well I'm back with a *brand* new question (yeah!)… I think one of the reasons of why Info() is giving me garbage for the Volume of the Disk, or better yet, why it looks like garbage to me is cuz' it doesn't point to a direct memory location…
Hmmm… Could you put that in Assem for me? I don't know where exactly to look to see if it's Selected David
Steve… Thanks…I'll give it a shot David
#Reading Validations?
Message #87956
Ello again… I just have 2 quick questions then I'll be out of your hair . 1). After a disk has been inserted and Validated by the system, how can I read the Volume? I tried using Info() but all the VolumeNode points to is a memory location looking like…
#Translate() HELP!!
Message #85757
What is the purpose of the Translate() function if the narrator.device can be programmed separately? I'm too confused cuz' I don't see how or why I need to use CMD_WRITE to the narrator.device if I have the Translate() function. Or does the CMD_WRITE/SendIO() just *setup* the translator to be used…
#PrintIText() = SLOW?
Message #69489
Ello again… I just finished a Directory-routine that uses a PropGadget to display the entries in a file. It works great except for one small problem… ITS TOO SLOW!!! Compared to other Directory Displaying routines that I see in everyday programs, minejust seems to creep along. So I was wondering…
Bob… Thanx for the reply. I guess I'll go for what feels logical and forget about what the book says. David
#ModifyProp HELP
Message #69130
Ello again… What byte sizes does the ModifyProp() command need for changing HorizPot,VertPot,HorizBody,VertBody? Cuz in the command it says that these need to be 1 byte size in length, but in the PropInfo Structure the sizes need to be 2 bytes. Or does the ModifyProp() command have NOTHING to do…

#Gadget Images
Message #65631
Keith… Thanks alot. I DOWnloaded a prog in LIB 13 that lets me draw simple yet multi-colored images, and it saves them in the correct form. Looking at the code that the prog dumps out I can understand how Images and PlanePick/PlaneOnOff works (sorta ). Thankyou for the informative reply.…
#New and desperate!
Message #4444
Hello, I'm new to the Amiga and I'm wondering what is the best assembler out on the market. Also are there any good books that are from a machine programmers point of view and not a C-programmers point of view concerning the insides of the Amiga. Thank you David Oldis
