/ Purpose      : Function-style macro to remove front and end matching quotes
/                from a macro string and return the result.
/ SubMacros    : %qdequote
/ Notes        : This is a function-style macro that calls %qdequote and uses
/                %unquote to remove the macro quoting so that you can use it in
/                ordinary sas code.
/ Usage        : %let str=%dequote(%qreadpipe(echo '%username%'));
/                %put  %dequote(%qreadpipe(echo '%username%')); 
/
