Trying to get AMOS ( I hope it's free now , as per BSD ). Download ISO  here on Ultimate , but cannot find where to start. Where is editor or anything similar?
DO anyone have step by step guide how to code "The world is HELL ;-) " for very first time , keeping in mind that I only have A1200 and WinUAE. Will grateful for any help as Blitz is to heavy and based on description I like AMOS better.

Hello Shahoff!

You can find the AMOS Professional archives (v1.0, v1.12 update, and v2.0 update) in the AMOS Factory / Development section of this web site.  These arechives contain .adf files that  you can use to install AMOS in an emulator or you can use the adf2disk tool from Aminet to write the disk files to real floppy disks for installation on a real Amiga.  Start with v1.0, install it, then install the 1.12 update followed by the 2.0 update.

There is a link to the AMOS Pro manual on the front page of the AMOS Factory.  It also has installation instructions and details of all the commands in AMOS.

But once you have AMOS installed, just start the program by clicking on the icon and the editor will start.  Type in "Print "The world is HELL :-)" and then click on the play button at the top of the editor screen.  If everything went correctly you should see the message printed in white on an orange background.

Thank you very much. I found Manual , I just did not realise that floppies are in use for install

[Sidewinder]

Ha!  Yes, we are pretty old school around here with the floppies and such!

I assume you got it installed and working?  Did your first program work ok?

[Shahoff]

Yes, thank you. Flying through the samples.   Need to find how to make and then control with AMOS I2C ports

[Shahoff]

Another option is to use RS232 and something like http://www.velleman.eu/products/view/?id=351282
But this is to simple

[Shahoff]

Already found bug in my opinion - "Print Len(Str$(5))"  = 2
So Str$ function return SPACE affront of any string Or this is as per design ?

This what I am getting if saving results to file "20 35 0D 0A"

[Sidewinder]

To my knowledge AMOS doesn't have I2C support directly.  It predates the I2C standard.  If you have an Amiga with an I2C port you'll need to figure out how to program it using the device driver or library that drives it.  AMOS can do this, but it's not so simple.

RS232 serial is supported.  See the serial commands in chapter 10 of the AMOS Pro manual.

The print and str$ are a little strange that way.  The extra space is for the sign but since the number you gave was positive, the sign is replaced with a space.  You can use the "Using" command to tell AMOS to print the + sign for positive numbers, but I'm not sure if that works with Str$() or only with Print command.

What do you mean by "saving results to file"?

[Shahoff]

N$=Str$("5")
Open Out 1 ,"test.txt"
Print #1,N$
Close 1


Hex 20 35 are the first symbols in file, so that how I know that Str$("5") returning [space][5]

[Sidewinder]

N$=Str$("5")
Open Out 1 ,"test.txt"
Print #1,N$
Close 1


Hex 20 35 are the first symbols in file, so that how I know that Str$("5") returning [space][5]

Ah!  I see what you mean now.  Right, Str$() inserts the space in place of the + sign.  You could try

Code: [Select]

N$=Str$(5)-" "

to remove the space if the Using command doesn't work with Str$().

Found this archive with books for system programming for Amiga

http://www.retro-commodore.eu/amiga-development/

[Shahoff]

never had this issue with Str$ before, but did test AmigaBasic from WB1.1 and yes , the same behaviour.

[Sidewinder]

That's quite a nice book archive!  I have a few of those books in my library.  They are worth their weight in gold!

I find it interesting that both AMOS and AmigaBASIC have the same behavior with Str$().  Maybe there is something about BASIC that requires or suggests that this be the standard behavior?

[SamuraiCrow]

BASIC on the C64 did the same thing with Str$.

Ok, STR$ sorted , but is it possible to change resolution of the editor ?
