OPEN 1,0 gives an error: "?MISSING FILE NAME ERROR IN"

mobluse commented 3 years ago

A line with OPEN 1,0 gives an error: "?MISSING FILE NAME ERROR IN", but doesn't give an error in VIC20, C64, or Commander X16.

This is used to INPUT#1,A$ a string from keyboard without showing a prompt ("? ").

Works for me on the current ROM master.

But it looks like you run x16emu. I run cbmbasic downloaded from here and compiled and tested in Raspberry Pi OS (most upgraded) today. Should I get a ROM from somewhere else?

git clone https://github.com/mist64/cbmbasic/
cd cbmbasic/
make
sudo mv cbmbasic /usr/bin/
cbmbasic

Hahahaha, I'm the best! I got this notification, and I confused X16 and cbmbasic! :D :D

Yup, this is a problem with the KERNAL emulation in C.
