Unite8Bit_**
Unite8Bit_**
The Unite8Bit_** instructions join bytes of data into a bit string.
* If you omit the input parameter, the default value is not applied. A building error will occur.
The Unite8Bit_** instructions join elements of array to join In[] to create a bit string in joined result Out.
Number of bytes to join Num specifies the number of array elements to join. First, In[0] to In[Num−1] are
joined to create a bit string with Num bytes. To this, 16#00 is added to the upper bytes for the number of
bytes of Out minus the value of Num. The result is stored in Out.
The name of the instruction is determined by the data type of Out. For example, if Out is the DWORD
data type, the instruction is Unite8Bit_DWORD.
