 DESCRIPTION
-<<isblank>> is a macro which classifies ASCII integer values by table
+<<isblank>> is a function which classifies ASCII integer values by table
 lookup.  It is a predicate returning non-zero for blank characters, and 0 
 for other characters.
 
-You can use a compiled subroutine instead of the macro definition by
-undefining the macro using `<<#undef isblank>>'.
-
 RETURNS
 <<isblank>> returns non-zero if <[c]> is a blank character.
 
+PORTABILITY
+<<isblank>> is ANSI C.
+
+No supporting OS subroutines are required.
