Hi,
I am trying to make a small program to dispalay an image onto the screen, but
when I run it, it doesn't show the image and the ERR file says:
C:\euphoria\BIN\Stuff\ex.err:1
C has not been declared
C:\euphoria\BIN\Stuff\ex.err:1
^
my code is:
include graphics.e
include image.e
atom gm
sequence graphic1
gm = graphics_mode(18)
clear_screen()
graphic1 = read_bitmap("1.bmp")
display_image({40,20},{graphic1[2]})
Any ideas why it doesn't work?

I have no idea how this code can produce that error message!
However,
display_image({40,20}, graphic1[2])
should work.

My guess is somehow you are trying to execute the ex.err file instead of your
program? Looking at the output it looks like ex.err is somehow trying to read
itself.

Are you using ed? It looks like you're trying to execute the ex.err
file. Close the ex.err file by hitting Esc-Q, then hit Esc-E to run
your app. This is probably a case of mistaken window.

Hi again,
the error output should be:
C:\euphoria\BIN\Stuff\ex.err:1
C has not been declared
C:\euphoria\BIN\Stuff\outputs1.ex:17
^
sorry for the mistake. Anyway line 17 is:
graphic1 = read_bitmap("1.bmp")
maybe I should start with something simpler.

Hi Vidi,
Your code works fine for me, if I change this line:
display_image({40,20},graphic1[2]) -- see just graphic1[2] without {}
But I can not reproduce that trick with err.ex anyway!

Hi there,
I can only guess, but it looks like maybe you wanted to include something
like:
include C:\euphoria\BIN\Stuff\MyFile.e
and instead you typed:
C:\euphoria\BIN\Stuff\MyFile.e
in which case i think you would get an error saying that 'C' wasnt
declared because Eu thinks it's a namespace prefix.
Just a guess...
See if you have anything like that in one of your files.
Take care,
Al
And, good luck with your Euphoria programming!

Hi again,
Ok, i just verified that that would cause that error message and
here's what i got:
C:\Euphoria\TestOthers\Other\UnusualError.exw:1
C has not been declared
C:\download\MyFile.e
^
The file was "UnusualError.exw" and
the only thing in the file was this:
--------------------------------------------
C:\download\MyFile.e
--------------------------------------------
exactly as shown without any 'include' keyword.
You'll have to check your files for any mistake like this.
Take care,
Al
And, good luck with your Euphoria programming!
