Rexx Programming/How to Rexx/quotation mark

In rexx, strings can be quoted using either singlequotes or doublequotes.

Quotation Marks Within a Literal String
In order to use literal singlequote characters within a string, the string can be enclosed using doublequotes:

say "Here's how we use an apostrophe within a string"

In order to use literal doublequote characters within a string, the string can be enclosed using singlequotes:

say 'Here we are using "doublequotes" within a string'

Back To Back Quotation Marks
It is possible to use backtoback quotation marks to represent a single quotation mark within the string:

say 'Here''s back to back' /* Note the back to back quotation mark for an apostrophe */
