Function
The lower eight bits of each of n 16-bit data entries in elements from head address [S] are combined. The
16-bit data after combination is stored in elements from head address [D]. The higher eight bits of every
source data entry from head address [S] are ignored.
An error is returned in the following condition. The error ag M8067 is set to ON to identify this error and
the error code is stored in D8067.
Error 6706 is returned when elements from head addresses [S] and [D] are out of range.

Application
The lower eight bits of each of the six data entries from head address D100 are combined into 16-bit data.
The result is stored in three elements from head address D120.
