Any set of characters (including no characters) enclosed by the single quote symbol (') is defined to be of type string in Darwin.

> thoughts := '';                               # an empty string
thoughts := 
> MyName := 'mike hallett';                     # a string
MyName := mike hallett
> MyAge := 'twenty eight';                      # a string
MyAge := twenty eight

Each item of type string is indexed and its individual components can be accessed in the same manner as one accesses the individual components of an array.

> MyName[6];
> MyAge[2];
