1. Euphoria bug found (warning system)
Hello again,
I ran into a bug in Euphoria's warning system that warns of an error
that isnt really there. I would bet other people ran into the same
thing.
Here's the code that emits a warning when the program tries to
exit:
constant MenuItem_Sep001=create(MenuItem,"-",FPUMenu2,-1,0,1,0,0)
The warning issued is:
"MenuItem_Sep001 not used"
The warning goes away if i change that single line to:
atom garbage
constant MenuItem_Sep001=create(MenuItem,"-",FPUMenu2,-1,0,1,0,0)
garbage=MenuItem_Sep001
Apparently, the warning system thinks constants arent used if
they are never used on the right side of another statement.

The symbol "MenuItem_Sep001" never appears
anywhere else in your program, so Euphoria issues
a warning about it. Most warnings are false alarms.
They are just meant to point out suspicious-looking
things in your code. Add "without warning" just before
this declaration, and you won't be warned about it
any more.
You have several other warnings besides this one.
If they are also false alarms, you can deal with them
in a similar way. It's best to put "without warning" in the
specific file that is generating a warning, but if you want,
you can just put "without warning" at the top of your
main .exw file, and turn off all warnings, everywhere.

Hi Al,

In relnotes.doc, we can see:
.....
Version 2.1 alpha-test release January 15, 1999:
.....
* Warnings are now displayed *after* your program
finishes execution, so they won't be erased by
clear_screen(), graphics_mode() etc. Some programs
now show warnings where none were seen before.
.....
So, in Eu 2.1, Eu 2.2 we can see Eu 2.0's FIXED bug,
not Eu 2.2, 2.1's own BUG, I think.
Then, is FIXED bug a bug? Yes it is. Isn't ?
