CREATED: 200702060959 ** Standard types and Constants string - “abc” char - #“a”, #"\163” bool - true, false int real word (unsigned integers) - 0w255, 0wxff

** Operators String concatenation - ^ Unary minus - ~ +, -, *, div, mod - for int and word +, -, *, / - for real =, <>, <, <=, >, >=

** Functions implode, explode ord, chr size, str abs

** Keywords local .. in .. end let .. in .. end val, val rec fun name paramters = expression fn parameters => expression

** Gotcha

• can also be used for symbolic identifiers such as ## or =# or even |#, therefore ‘‘always put a space before a hash’’
