What are all the valid ways to quote literal strings when assigning them to variables in unibasic on Unidata?

I use double quotes, single quotes, and backslashes.

"Hello"

'Hello'

\Hello\

of course the functions DQUOTE and SQUOTE can be useful too.

Shawn,

For consistency I never use a  '  but rather ".  

COLOR = "BLUE"   ;* preferred method of the "

COLOR = 'RED'    ;*  never used. 

COLOR = \YELLOW\   ;* never use to assign a variable but preferred method to execute a TCL statement or an Operating system command. 

STMT = \SELECT FILENAME WITH COLOR = "BLUE" \   ;* preferred method of the \    It's much easier to read and easy on the eyes.
