split file based on file size in Korn script

Thanks, but I already know how to use split -l --what I'm looking for is how to get the size of the file and pass the number of lines (or half the number of lines) to the split -l command in the script.

I was thinking this might work, but it doesn't:
awk < mylist.txt '{if ($5>78000000) "split -l $5/2 $NF $NF"; rm $NF}'

So I need to know how to get the $5 and $NF values into the shell script so I can run it....

Thank you.
