String

<=   =>

Characters bracketed by quotes create a string.

   char =. 'Q'
   chars =. 'this is a list of characters' 

The quotes are not displayed when the string is displayed.

   char
Q
   chars
this is a list of characters

The quote starts and ends a string. A pair of quotes indicates that the quote character itself is in the string.

   'put 2 ''s to get 1 '' in the string'
put 2 's to get 1 ' in the string

An unmatched quote is an error.

   abc =. 'asdf
|open quote

A string can be empty.

   abc =. ''

A string is also referred to as a literal constant or as a character constant.
