writing batch files is NOT like learning to ride a bicycle.......

Years of gui-happy program operations have left my once reasonable acumen and the ability to dash off a
batch file in a literal shambles.  
I wrote a 'getdate.bat' to prep the system date for filename usage in win 7 a few years ago, but it was
not nearly as elegant as those i have seen here using the for/in/do statements.  The following batch
file is only included to give an idea of where i got to in batch files. and most were written 20-25
years ago.  But i did manage to fumble through this one a few years ago.......  
~~~~~~~~~~~~~~~~~~
echo %date%

set mth=%Date:~4,2%
set day=%Date:~7,2%
set yr=%Date:~10,4%

echo %mth%%day%%yr%

set shortdate=%mth%%day%%yr%

echo %shortdate%

Pause

~~~~~~~~~~~~~~~~~~

Now, I realize that i have forgotten most batch principles and commands.

I want to write front-end bat for a rather large command-line program called youtube-dl  which, when the
.bat is initiated does a few things, and stops multiple times for keyboard input along the way to
execution, and then continues on with that new information.
I will start out a command line with boilerplate of "youtube-dl -f 18 -i".

Any help?
