Has anyone tried AI with PICBASIC

The question is, from where it took "0", is there any programming language that can make ASCII to decimal conversion that way?

nearly all can do that, except that in C,C++ etc it would be '0' not "0" [single quotes is a chr 'literal' double quote is a null terminated "string" c-str]

I'm not mixing, but with PBP

X-"0" gives syntax error while compiling.

I am pretty sure it does not. Compiles just fine because "0" is in fact 48. So if X-48 compiles it will also compile X-"0".

If course to have correct results you should not mix 0 (zero) with O (capital letter O) because they have different ascii value. But all compile fine.
