Assign double quote character to a string parameter

Does anyone know of a way to assign a double quote to a string parameter via relations?  I can manually create a new parameter and add a double quote to it, but not programmatically.

My current workaround is to manually create a parameter with a value of " and then use this parameter any time I need a double quote character.

DBL_QUOTE = "    (manually created – doesn’t work in a relation)

STRING_PARAM = DBL_QUOTE + "BLAH BLAH BLAH" + DBL_QUOTE

Yes, I NEED the double quote in the final string.  The ASCII value (34) is critical.

Thanks!
