Comparisons

%BQUOTE and %NRBQUOTE do not require that you mark quotation marks but
matching parentheses are required.

%NRBQUOTE and the %SUPERQ function mask the same items. However,
%SUPERQ does not attempt to resolve a macro variable reference or a
macro invocation that occurs in the value of the specified macro
variable. %NRBQUOTE does attempt to resolve such references
