to read starting from %IB1 up to %IB127. Likewise, %QB0 would be used to represent how many
bytes of information to write starting from %QB1 up to %QB127.
NOTE: When using a Short String Data Type, the 1
st
byte of each slot is reserved for the
Length field. The remaining bytes will be used for the actual data.
