So when the foreach loop finishes it restores the undef value to $_. Thanks.

[james28909]: check if it is a hash or an array ect with ref in one sub.
[james28909]: like all the subs calling get_data get_array get_ect, you could just use get_data. once you send the data to get_data, check if it is a hash or an array ect. and do functions for each, in one sub
[james28909]: that looks like it would be alot more work than just renaming the sub though lol
[Lady_Aleena]: james28909, did you even look at the subs?
[james28909]: yes
[Lady_Aleena]: And you see how the first two are vastly different than the third, right?
