Here it starts with some HTML Text
All values should be undefined:
$a = [+ $a || '' +]
$b = [+ $b || '' +]
$c = [+ $c || '' +]
$d = [+ $d || '' +]
$e = [+ $e || '' +]
First of all assign a value:
[- $a = '(this is the value in $a)' -]
Now we have some 'Umlaute':
[- $b = "$a äöü" -]
Now lets look what we are getting from this:
[+ $a +] [+ $b +]
And now a and b together: [+ "$a$b" +]
Here we have some HTML tags within the perl code, Embperl will delete them!
[+ $c =
6 + 17 * 3 +]
Embperl will also translate HMTL escapes to the right characters i.e. $a < 6 will get the perl expression $a < 6:
[- $e = 2 -]
[+ $d = $e < 6 +]
Now they should have a value
$a = [+ $a +]
$b = [+ $b +]
$c = [+ $c +]
$d = [+ $d +]
$e = [+ $e +]
[- $a = 1; $b = 0; $c = 5; $d = 'txt' -]
