In SAS/AF Software, declaring character attributes with a maximum length
in CLASS syntax will have no effect on the maximum length of the
attribute when the class is loaded at runtime.

For example, in the following logic that creates class X with the
character attribute ATTRSTR and the method M which executes the MLENGTH
function in SAS Component Language (SCL) to return the maximum length of
ATTRSTR,

   class x;
   dcl char(14) attrstr;

   m:method;
      dcl num len;
      len=mlength(attrstr);
      put len=;
   endmethod;
   endclass;

the value of the variable LEN will be 32767 when you execute method M on
class X.  The MLENGTH function will always return 32767 when it's
argument is a class attribute of type character.

Please refer to SAS Note SN002955 for a compilation issue with the
example code listed above.
