Ok, so the ASC command gets the ASCII code of the character in the string, the ASCII code is a value that ranges from 0-255 that corresponds to each character, so for example the character "A" has a value of 65.

The MID$ and LEFT$ commands just look at one part of the string rather than the whole string, in this case we only want 1 character since ASC only accepts 1.
