Il is an esolang was planned to be an esolang with identical vertical lines with different codes, but I didn't find any other than l (108 or U+006C) and I (73 or U+0049)

Language Description

Il is output one number using incrementing or decrementing. It has not special command for outputting, but the end of code outputs the N. Il just in three (or, mahbe, two) commands:

Command	Description	Short description	Short example
I(73)	Increments the current number by 1	INC	IIII - XKCD
l (108)	Decrements the current number by 1	DEC	llll - antiXKCD (-4)
(10, or end of code)	Outputs the current number as number (Not ASCII!)	print(n)	I - output '1'

Shorter, in your words

I (big "i") is +1
l (small "L"> is -1
when code ends number outputs

Implementation (interpreter)

As code

Python

num=0
code=input()
for c in code:
	if c=="l":
		num-=1
	elif c=="I":
		num+=1
print(num)

more compact:

n=0
for c in input():
    n+=c=="I"
    n-=c=="l"
print(n)

Examples

XKCD Random Number

with comments it will be:

IIII        increment 4 times
end of code outputs it

Without em:

IIII

Hello, World!

With comments:

IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII
increment by 72.
just output 72.. but, this is "H"'s ASCII code!

Without:

IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII
