eaf ...Where is o

The title of this article is not correct because of technical limitations. The correct title is actually eaf..Where is o?.

eaf ...Where is o? is an esolang by User:Yoyolin0409. It's like a deadfish, but without any deadfish commands(d, i, s, o, h), (So where exactly is the "o" in the word "deadfish"?). Of course, it would be a shame if it were truly useless, so I assigned the following functions to the commands e, a, f, "THERE IS NO O", ...:
e must be inserted at the beginning of the program
a increments the temporary register by one. The value of this temporary register ranges from -255 to 256, and it will overflow into a negative number.
f must be inserted at the end of the program.
"THERE IS NO O" output the temporary register's value.
... will output the result of converting the register number to ASCII.

Example

Output 1

ea"THERE IS NO O"f

Output 100

eaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa"THERE IS NO O"f

Output -255

eaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa"THERE IS NO O"f

Note

Anyone with a discerning eye can see that EAF is the result of Deadfish with d, i, s, and h removed, but some AIs just can't see it.
