Devpac beginner troubles

[jonesypeter]

Hi,

I have done a small amount of assembler on the ZX Spectrum, but as I had an Amiga 1200 back in the day, I thought I would start learning the basics.

I'm using WinUAE with A1200 emulation (40.68 Kickstart) and Workbench 3.1. I'm using Devpac Lite that came with Amiga Shopper magazine and the version is 3.12. Its the same as normal Devpac but is restricted to 200 lines, and won't create an executable file.

I'm following a beginners guide in Amiga Shopper issue 43, page 54.

The code is as follows:

move #2, d0
move #2, d1
add d0,d1
rts

When I assemble the code I get 'Error: Line malformed at line 1 in file Untitled.s


The '#' is highlighted as being in error.

Can anyone guide me along the right path.

Very many thanks

I don't know devpac specifically, but could it be because you haven't given the size directive to move/add? eg:

move.w #2,d0
move.w #2,d1
add.w d0,d1
rts

There are 3 possiblities for the size, .b (byte, 8 bits), .w (word, 16 bits) or .l (long, 32 bits)...

The leftmost column is reserved for labels. Instructions should go into the second column. That is, put a space or a tab-stop upfront the instruction.

Thomas, you are a genius. Thank you!

To get you started you can always check out my AmigaGameDev site which will probably help you along. Episode 1 shows you how to get a cross dev platform working on Windows so you may want to skip that and go to Episode #2.

You can ask questions on my Discord too if you get stuck where I often hang about.
