So I just want to make sure I follow this. You converted the numbering of lines to base 44 (that's what the NR % 44 was, I gather) so that you could delete any line with a ones place of 9 or under? What's the 0 {next} 1 bit, if you don't mind my asking?
Also, thanks very much for your help!

NAME
args - manipulate and output command arguments. SYNOPSIS
args [options] args... DESCRIPTION
This command is used to manipulate and echo command line arguments to standard out. This can include adding quotes around each argument passed or a separator, or to output each argument on a separate line. The program source also offers a basic example of how to use shell argument parsing and localization in ucommon. OPTIONS
--delim=char Set a deliminator character, such as ',', to use between each argument when outputing arguments. --directory If argument is a directory, list directory contents as arguments. --follow If argument is a directory and a symlink, follow symlinks recursively. --lines Output each argument on a separate line. --quote=char|pair Set a quote or special leading and trailing pair of characters to surround each argument with when output. A typical use might be --quote=() to surround arguments in parenthesis. --recursive If argument is a directory, recursively scan directory and any subdirectory contents as arguments. --reverse Reverse order of arguments. --help Outputs help screen for the user.
