LET - QB64Official/qb64 GitHub Wiki
             The LET is a useless statement designed by cavemen when they started programming.
Syntax
[LET] variable = expression
Description
LET a = 12 is the same as a = 12, but wastes 4 extra bytes of program space. 
- LET is optional, it's the only keyword where the entire keyword is optional :-)
