Cautions
When handling 32-bit data in structured programs, you cannot specify 16-bit devices directly, different from
simple projects. Use labels when handling 32-bit data.
You can specify 32-bit counters directly, however, because they are 32-bit devices.
Use global labels when specifying labels.
Program example
In this program, the exclusive logical sum is obtained using each bit of word [unsigned]/bit string [16-bit] data
stored in devices specified in
using the data type of data stored in devices specified in
