1. Pixel command
Hey to all.
I seem to be having some difficulites. I recently purchased the =
Complete Edition of Euphoria, and installed that on my machine.
I moved all the files I had accumulated recently into
the new Euphoria directory, and then deleted everything
that had just been replaced with the Complete Edition.
Now, for some reason, when I try to run a program with the
pixel command in it, it gives me an error message stating:
"Pixel not declared" I went into GRAPHICS.E and looked,
and there is no pixel command. I looked at the constants
at the top, and they said "--M_PIXEL --obsolete" and
"M_GET_PIXEL --obsolete" I wonder if this has anything to do
with it. If someone could just send me the code I need to put
into GRAPHICS.E, it would be greatly appreciated.
Thanks for any help.
Regards,
Bryan Watts

In moving from Euphoria 1.5 to Euphoria 1.5a, pixel() was
changed from being a Euphoria routine in graphics.e
to being a routine that is built in to ex.exe. (The same thing
was done to get_pixel(), mem_set() and mem_copy()).
This was done to boost performance on games etc.
If you mix up ex.exe for 1.5 or earlier with graphics.e for 1.5a you will
get the error "pixel not declared" when you try to use pixel(), because
pixel() will not be defined in graphics.e *or* in ex.exe.

Don't do that. If you are really running ex.exe for 1.5a, then
pixel() will *always* be declared. I strongly suspect that you
still have ex.exe for 1.5 on your PATH. Only ex.exe for 1.5
or earlier could say that pixel() is not declared.
Type:
ex <Enter> <Enter>
to see which version you are running.
The proper procedure for upgrading is to:
1. Run install.bat for 1.5a and let it rename your existing
EUPHORIA directory as FUPHORIA.
2. Copy from FUPHORIA any special files that you may have added
to EUPHORIA\INCLUDE or other directories. *Do not* simply overwrite
any of the 1.5a include files. If you have added your own routines
within those files, you must carefully cut and paste them into the
new 1.5a include files.
As a general rule, it's better to make your own .e file, than it is
to modify a standard .e file.
