AryLRC_**
The AryLRC_** instructions calculate the LRC value for an array.
* If you omit the input parameter, the default value is not applied. A building error will occur.
The AryLRC_** instructions calculate the LRC value (exclusive logical OR) of Size array elements of
array to process In[] starting from In[0]. 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 AryLRC_WORD.
Always attach the element number to in-out parameter that is passed to In[], e.g., array[3].
