Talk:Perl Programming/Scalar variables
Page contents not supported in other languages.
I did not understand this note box very well. Can some one please clear it up for me?
| Note The two 'Comparison' operators are slightly different from the rest. Rather than returning only 1 or 0, these operators return -1 if the left argument is greater than the right argument, 0 if they are equal, and 1 if the right argument is greater than the left argument. |
maybe it's my setup, but i have trouble executing the code in the examples (even the Try It examples). it turns out i have to add "my" before variables - should this be part of the tutorial?
There are labels about a merger of this part withPerl Programming/Basic Variables. I think that it is agood idea to merge them.--Sae1962 (discuss •contribs)15:42, 12 February 2015 (UTC)
