HELP APOSTROPHE Steven Hardy, March 1982 Apostrophes have a special significance in POP-11. The character ' is used to delimit strings, for example 'this is a string' The character ` is used to indicate 'character constants', for example: `a` (a character constant) See REF *ITEMISE for details of itemisation in POP-11, and TEACH *APOSTROPHE for a tutorial introduction to the use of apostrophes.
