+FUNCTION
+	<<isascii>>---ASCII character predicate
+
+INDEX
+	isascii
+
+ANSI_SYNOPSIS
+	#include <ctype.h>
+	int isascii(int <[c]>);
+
+TRAD_SYNOPSIS
+	#include <ctype.h>
+	int isascii(<[c]>);
+
+DESCRIPTION
+<<isascii>> is a macro which returns non-zero when <[c]> is an ASCII
+character, and 0 otherwise.  It is defined for all integer values.
+
+You can use a compiled subroutine instead of the macro definition by
+undefining the macro using `<<#undef isascii>>'.
+
+RETURNS
+<<isascii>> returns non-zero if the low order byte of <[c]> is in the range
+0 to 127 (<<0x00>>--<<0x7F>>).
+
+PORTABILITY
+<<isascii>> is ANSI C.
+
+No supporting OS subroutines are required.
