| <<isprint>> is a macro which classifies ASCII integer values by table |
| lookup. It is a predicate returning non-zero for printable |
| characters, and 0 for other character arguments. |
| It is defined only when <<isascii>>(<[c]>) is true or <[c]> is EOF. |
| It is defined only if <[c]> is representable as an unsigned char or if |
| <[c]> is EOF. |
| You can use a compiled subroutine instead of the macro definition by |
| undefining either macro using `<<#undef isprint>>' or `<<#undef isgraph>>'. |
