+
+DESCRIPTION
+<<isblank>> is a macro 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.
