It never wraps. Tried before editor, after editor, after CPU RESTART and a power cycle.
OPTION DISPLAY 50, 152

Adding a pause shows the last character of the current "i" number printing to the screen on the right until the loop ends, hence the last 0.


interesting... with GFXterm set to 80 columns, and an MX170 attached i see:

that is, all 200 numbers are visible in the terminal. from what you are seeing, i would say that later versions of mmbasic are no longer expecting the terminal (or terminal emulator) to automatically wrap onto the next line when the cursor goes off the rhs of the screen. instead mmbasic is now counting characters as they are being outputted, and either not transmitting beyond the number of columns set with OPTION DISPLAY lines, columns, or prefixing every character it believes is beyond the number of columns set with a backspace.

one would be hard pushed to find another implementation of basic (either designed for serial terminal I/O or for driving a screen) that does this!


cheers,
