You don't need to (cannot) assign to InpAscii. Just miss out that last
line. You have already done what you want in the declaration, so that
last line amounts to "$1 := $1".

"Dearly beloved, avenge not yourselves, but rather give
place unto wrath. For it is written, Vengeance is
mine; I will repay, saith the Lord. Therefore if thine
enemy hunger, feed him; if he thirst, give him drink;
for in so doing thou shalt heap coals of fire on his
head. Be not overcome of evil, but overcome evil with
good." Romans 12:19-21
