DESCRIPTION
|
|
<<toascii>> is a macro which coerces integers to the ASCII range (0--127) by zeroing any higher-order bits.
|
|
|
|
You can use a compiled subroutine instead of the macro definition by
|
|
undefining this macro using `<<#undef toascii>>'.
|
|
|
|
RETURNS
|
|
<<toascii>> returns integers between 0 and 127.
|
|
|
|
PORTABILITY
|
|
<<toascii>> is not ANSI C.
|
|
|
|
No supporting OS subroutines are required.
