1. ED BUG
I accidentally introduced a bug into the 1.4b version of ed.ex.
David Cuny reported it. The problem occurs if you type an unsupported key
combination (e.g. Alt-F) that generates a key code greater than 255.
If the editor is running with color syntax highlighting, it
will crash. This could be nasty if you have entered a
lot of changes without saving.
Fortunately the fix is very easy.
edit the file: euphoria\bin\ed.ex
go down to: function good()
replace the line that says:
elsif key >= ' ' then
with:
elsif key >= ' ' and key <= 255 then
This will cause keycodes greater than 255 to be
ignored. (actually you'll get a warning message)
In 1.4a it used to say 127 rather than 255, but I
wanted to allow people to enter keycodes greater
than 127. You can enter special characters from 128 to 255
by pressing Alt and 3 digits on the numeric keypad.
This is a feature of DOS and Windows.
I will fix the 1.4b release on the WEB page in the next
couple of days. I won't bother to call it 1.4c since
this will be the only change.
