  * indicates a required field

Consider the following example:

   %let a=abc;
   %macro readabc;
     %put testing;
   %mend readabc;
   %read&a

In Version 6 and 7 the trailing &a would resolve before trying to invoke the macro but this was incorrect. To be compatible with release 5.18, Version 8 tries to invoke the macro before resolving the macro variable 'a' above.

The workaround to emulate the Version 6 and 7 behavior requires use of
the %UNQUOTE and the %NRSTR functions as demonstrated below.

   %let a=abc;
   %macro readabc;
     %put testing;
   %mend readabc;
   %unquote(%nrstr(%read)&a)

Due to customer feedback, the V6 behavior will be reinstated for release 8.2.
