Literals

Literals are LDL+ primitives used in logic statements to specify values. They are used when appropriate within logic statements to denote values that do not change.

A literal can be either a string or numeric literal. The Boolean literals ‘true’ and ‘false’ can also be used. As string literals, they can have character significance. However, string literals which contain valid numeric syntax might be used wherever a numeric literal is allowed. As numeric literals, their values have numerical significance.
