The charizing operator can be used only with arguments of macros. If #@ precedes a formal parameter in the definition of the macro, the actual argument is enclosed in single quotation marks and treated as a character when the macro is expanded. For example:

#define makechar(x)  #@x  

causes the statement

a = makechar(b);  

to be expanded to

a = 'b';  

The single-quotation character cannot be used with the charizing operator.
