The Atari Bookkeeper

Today we dip into the world of the Atari 800, but instead of starting with a game, like a sane person, peterb decides to look at a double-entry accounting program from 1982: The Atari Bookkeeper. Invalid input is beeped. Many disks are swapped.

Americans missed out on the (Acorn) BBC Micro. Now there was a programmable computer. A proper procedural BASIC, and built in assembler. Built like a tank. Amazing hardware.

I've heard so much about the Acorn but never used one outside of emulation. Really enjoyed the TV movie with Martin Freeman, "Micro Men."

On the C64 if you wanted to see if a program was written in BASIC you would just try hitting the "RUN/STOP" key. Unless that had been disabled that would get you to a BASIC prompt and you could just type LIST and see what came up. I have no idea what the Atari equivalent would be or even if there is one though.

I should absolutely figure out how to do this on the Atari!

Only used Apple so same experience as you. It looks like the display mode isn't correct. That last screen (at 24m) looks to have been designed for something other that 40 columns. The column horizontal dividers are wrapping as if you're running an 80-column program in a 40-column mode. I wouldn't be surprised if the input scrolling would be resolved by figuring out if modes are a thing on Atari and how to change.

OMG that could be it. I'll investigate further. (Although, if this is the ledger, I think what we're seeing is basically the output that was "supposed" to have been sent to the (nonexistent) printer)

Are you emulating on Windows? You maybe getting a side effect of the carriage-return + line feed, producing a new line on entry. Is this your first time using this emulator? Just some minimum geeky guesses. Thanks for sharing.

[@TeaLeavesProgramming]

Mac, but CR+LF would make perfect sense as an explanation!

@@TeaLeavesProgramming I'm not in a position to play around with emulators for right now, but you may find an option for correcting that, as it's a pretty old problem to interpret pressing the enter-key across systems. I would either check emulator configure options or read through the config file. As a long time Linux user, I can honestly say, I've found these type of issues are usually already predicted by the people creating the emulation software.
Hope that helps.
Oh, unrelated, but as a former, considering future again, bookkeeper, having to put in the cents alongside the rest of the number is still common in that type of software, rather than pressing the period. Especially notable, as the actual system is not one with 10-key in the first place, saving the time of dropping to another row. When you get used to it, you would be amazed how annoying it is when other software doesn't do that.

Apple 2 vs Atari? Try being a Trash-80 guy!

[@TeaLeavesProgramming]

In the years before I got my Apple 2, my favorite leisure activity was hanging out at the Radio Shack and dorking around on the TRS-80 Model III.
One of my friends had a TRS-80 Color Computer and it might unironically be my favorite machine from that era.
