SP.FREAD
(g) With the High Performance model QCPU/Process CPU/Redundant CPU/Universal model QCPU/LCPU whose first
5 digits of the serial number are "01112" or later, it is possible to divide read operation into multiple times.
[Specify the row desired to start read.]
[In the continuation mode, read continues from the end of the previous read position.]
• When read is performed in the continuation mode, the previous addition cannot be made normally if the "execution
type", "No. of columns designation" and "data type specification" settings differ from those at the previous time.
• The previous addition cannot be made normally if the SP.FREAD instruction or SP.FWRITE instruction with another
setting is executed while data is being read continuously in the continuation mode.
