Mantissa portion sign
(3-2) When the variable type is Array or Record
The format data explained in SimpleVariable is divided into the number of elements. When
the data length of one element is an odd number of bytes, a valid value is not set for the
element’s first byte.
Example: When the VariableString array value is "ABCDE," "FGHIJ," then the setting is as
follows.
'B'
'A'
'D'
'C'
'J'
