RESULT:

Ternary=True

TEST=False

 

Why:     Ternary <> TEST    

?

The ConsoleWrite function returns the amount of data written.

If it's different from 2 then $a <> $b.

Br, FireFox.

Your condition is not what you think it is:

$a = 1
$b = 2
$a = $b ? ConsoleWrite('Ternary=' & True & @CRLF) : ConsoleWrite('Ternary=' & False & @CRLF)
ConsoleWrite('TEST=' & ($a = $b) & @CRLF)

$a = 1
$b = 2
($a = $b) ? ConsoleWrite('Ternary=' & True & @CRLF) : ConsoleWrite('Ternary=' & False & @CRLF)
ConsoleWrite('TEST=' & ($a = $b) & @CRLF)

It is worth noting that this is only when assigning. For example the following will do the $a=$b before the ternary operation.

$a = 1
$b = 2
ConsoleWrite('Ternary=' & ($a = $b ? True : False) & @CRLF)
ConsoleWrite('TEST=' & ($a = $b) & @CRLF)

Or try it this way.

$a = 1
$b = 2
($a = $b) ? ConsoleWrite('Ternary=' & True & @CRLF) : ConsoleWrite('Ternary=' & False & @CRLF)
ConsoleWrite('TEST=' & ($a = $b) & @CRLF)

It works better when you put the condition inside parentheses because it does the comparison before attempting the rest of the line.

Ahem, just what I was pointing out...

Thank you all for your enlightenment.
