• When read is performed in the continuation mode, the previous addition cannot be made
normally if the "execution type", "column 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.
