Re: Jon Relay's Apple II Info Archives: Zero Page Addresses
Here are some more adjustments or clarifications to the zero page
memory usage table...
$22 - Top Margin (0 - 23, 0 is default, 20 in graphics mode)
$D8 - Error Flag (>=128 if error handler active)
$F3 - Text OR mask (for flashing text)
$F4-$F5 - address of error handler (points to line number after ONERR GOTO...)
