in thread Get the length of a list.

You are correct choroba.
Thanks for pointing out my error :)


perldata - Context highlights the difference between scalar(array) and scalar(list):
If you evaluate an array in scalar context, it returns the length of the array.
(Note that this is not true of lists, which return the last value, like the C comma operator,
nor of built-in functions, which return whatever they feel like returning.)

[Lady_Aleena]: Um, what?
[james28909]: check is is data or hash or array and do tasks then return needed data
[Lady_Aleena]: james28909, you might want to look at the other two on my scratchpad.
[james28909]: after you send to a sub, you can check if it is array or ref ect with ref
[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
