Re: Given When Syntax

I'm mobile and can't spot or test your problem.

Normally I recommend replacing given/when with for/if-constructs.

But in this particular case I don't understand why you are not simply using an array or a hash, holding the number's names.

edit

Ehm... did you activate switch?

use feature "switch"; or use 5.010;

update

  DB<103> @num=qw/Zero One Two Three Four/
 => ("Zero", "One", "Two", "Three", "Four")

  DB<104> $var=2; print "$var is $num[$var]";
 => 1
2 is Two

Hi Rolf. As I mentioned to HazyLife, I could have used Switch and I also thought of using an array, as you have demonstrated above, but in the actual program I'm running I'm already in the middle of hash. I will try if I can do this there, however. I'm trying to do this the most efficient way and I don't have a whole lot of PERL experience. Thanks for replying!!	[reply]

I think you are getting it wrong, Given/When are activated by the feature pragma with the keyword `switch` or with an indication of the first Perl version which supports it.(not a Switch module) The deprecation also affects Given/When, because of the built-in use of smartmatch. We had a discussion recently, should be easily found. In the post above I updated a link to a thread showing how to easily emulate Given/When with For/If! HTH! :) Cheers Rolf ( addicted to the Perl Programming Language)	[reply] [d/l]
