Converts a number to a two-byte string.
Synopsis
$ZWCHAR(n)
$ZWC(n)
Parameter
n A positive integer in the range 0 through 65535. It can be specified as a value, a variable, or an expression.
Description
$ZWCHAR returns a two-byte (wide) 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. It is the functional equivalent of:
   WRITE $CHAR(n#256,n\256)
If n is out of range or a negative number, $ZWCHAR returns the null string.
Example
The following example returns the two-byte string for the integer 25185:
   WRITE $ZWCHAR(25185)
 
returns: ab
Notes
$ZWCHAR and $CHAR
$ZWCHAR is similar to $CHAR except that it operates on two byte (16-bit) words instead of single 8-bit bytes. For four byte (32-bit) words, use $ZLCHAR; For eight byte (64-bit) words, use $ZQCHAR.
$ZWCHAR and $ZWASCII
$ZWASCII is the logical inverse of the $ZWCHAR function. For example:
   WRITE $ZWCHAR(25185)
 
returns: ab
   WRITE $ZWASCII("ab")
 
returns: 25185
