**_TO_STRING (Bit String-to-Text String Conversion Group)
**_TO_STRING (Bit String-to-Text
String Conversion Group)
These instructions convert bit strings to text strings.
* The valid range depends on the data type of In. Refer to Function for details.
These instructions convert a bit string, In, to a text string. The hexadecimal number given in In is output
to conversion result Out as a text string. The #16 prefix of the hexadecimal number is not output to Out.
A NULL character (16#00) is placed at the end of Out.
The text in Out is left-aligned. If the value in In requires fewer digits than provided by the data type of In,
the upper digits of Out will contain 0. In other words, the unused digits are padded with zeros. The num-
ber of bytes in Out (including the NULL character) will always be one greater than twice the number of
bytes in In.
The name of the instruction is determined by the data type of In. For example, if In is the WORD data
type, the instruction is WORD_TO_STRING.
