I`m trying to sort some numerical values in ascending order from some
output that I print to screen. Would anyone know how to do this?

I guess you mean "from some input source before I use it as output that
I print to screen", right?
Look into getting you numbers into an array variable like @numbers, and
then sorting them with
@sorted = sort { $a <=> $b } @numbers;
`sort` by itself sorts alphabetically, so `35` would be before `7`, so
that is why you need to include the block. Read the documentation on
`sort` (perldoc -f sort) for greater insight into the function and how
to use it in this fashion.

This sounds familar. I will check the docs and see what it says
about the sort function. Thanks
