$ZQCHAR (ObjectScript)

Converts a number to an eight-byte string.

Synopsis

$ZQCHAR(n)
$ZQC(n)

Parameter

Argument Description
n An integer in the range -9223372036854775808 through 9223372036854775807. It can be specified as a value, a variable, or an expression.

Description

$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.

$ZQCHAR issues a <FUNCTION> error if n is invalid.

Example

The following example returns the eight-byte string for the integer 7523094288207667809:

   WRITE $ZQCHAR(7523094288207667809)

returns: “abcdefgh”

Notes

$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:

   WRITE $ZQCHAR(7523094288207667809)

returns: abcdefgh

   WRITE $ZQASCII("abcdefgh")

returns: 7523094288207667809
