Converts an integer to the corresponding eight-byte string.
$ZQCHAR returns an eight-byte (quad) character string corresponding to the binary representation of n. The bytes of the character string are presented in little-endian byte order, with the least significant byte first.
If n is out of range $ZQCHAR returns the null string. If n is zero or a non-numeric string $ZQCHAR returns 0.
$ZQCHAR and $CHAR
$ZQCHAR is similar to $CHAR except that it operates on eight byte (64-bit) words instead of single 8-bit bytes. For 16-bit words use $ZWCHAR; for 32-bit words, use $ZLCHAR.
$ZQCHAR and $ZQASCII
$ZQASCII is the logical inverse of the $ZQCHAR function. For example:
