how to escape special chars

I am trying to add a custom property which needs quote marksembedded in it thusly...
prop = DrawingDoc.AddCustomInfo3("", PropName(11),swCustomInfoText, "\$PRP:\" SW-Current Sheet\" ")

However, the method I've used in so many other (Non SW) places doesnot work, namely preceding the character with a backslash.
How do I do this in an SW macro?
