MS-DOS 6.22 (excluding any typos as I rewrote it, I only did a proof of concept with a few words but it seemed to work). @echo off mkdir c:\t echo prompt echo %1 $g C:\t\%1 >> c:\temp.bat command /c temp.bat %1 > c:\h.bat del c:\temp.bat type words.txt | find /V "a" | find /V "s" | find /V "d" | find /V "f" | find /V "g" | find /V "h" | find /V "j" | find /V "k" | find /V "l" | find /V "z" | find /V "x" | find /V "c" | find /V "v" | find /V "b" | find /V "n" | find /V "m" > c:\words2.txt echo > h.bas DIM word as STRING echo >> h.bas OPEN "C:\words2.txt" for INPUT as #1 echo >> h.bas DO WHILE NOT EOF(1) echo >> h.bas INPUT #1, word echo >> h.bas CMD$ = "C:\h.bat " + word echo >> h.bas SHELL CMD$ echo >> h.bas LOOP echo >> h.bas CLOSE #1 echo >> h.bas SYSTEM qbasic /RUN c:\h.bas dir /OS /B c:\t @del c:\t\* @rmdir c:\t @del c:\words2.txt @del c:\h.bat @del c:\h.bas You can play with MS-DOS 6.22 in a virtual-machine-in-browser here[1].

The qwerty filtering is a chain of `find /V "a"` for excluding each of the other rows cough. I then couldn't loop over the file lines without QBASIC.
