if I make a script that says:

 
$pi ||= 3
print $pi;
[download]

I'll get back something like

 
syntax error at or.pl line 1, near "|| ="
[download]

So the way its written won't work

I wonder if this will be different if your testing a hash, since you use exists() instead of defined();

syntax error at or.pl line 1, near "|| ="

That's a Perl4 (or earlier) error message. Please upgrade to a version of Perl that was released sometime after the Spice Girls hit the pop charts.

merlyn, I've gotta say this was a great laugh for this morning =] Maybe future versions of perl should be named after the current music sensation of the time of release. =]

Perl 4 didn't support overloading = with ||?

If so, did it support the = and || operators?

And if so, couldn't we use this: $value = $value || 'DEFAULT'; to accomplish the same thing?

(Not that I don't support the idea of upgrading Perl to a recent version, but the Spice Girls are pretty old news themselves. *grin*)

The code that you provide there is not the code giving you that error message. The error message you list indicates that you have an extraneous space in ||=. ||= should not have any spaces.

The code you provided will give you an entirely different error, namely syntax error at - line 2, near "print" since you didn't have a semicolon at the end of the first line.

ahh,

huh,

hmm,

that's a weird place for spaces to make a difference, since,

 
$pi         =           $foo         ||     67;
[download]

will work, oh well, thanks everyone,

thinks for a minute, ....

Ohhh i see, ||= is an assignment operator, sweet cake, thanks everyone
