| DESCRIPTION |
| <<isalpha>> is a macro which classifies ASCII integer values by table |
| lookup. It is a predicate returning non-zero when <[c]> represents an |
| alphabetic ASCII character, and 0 otherwise. It is defined only when |
| <<isascii>>(<[c]>) is true or <[c]> is EOF. |
| alphabetic ASCII character, and 0 otherwise. 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 the macro using `<<#undef isalpha>>'. |
