Handling Space Characters
in Downloading
■ Space characters used as padding characters
A data file can be downloaded with System Mode or an XFILE statement according to the
communications protocol which is designed to eliminate space characters padded in the tail of
each data field. That is, such space characters in a data file will not be handled as data in the
BHT-3000/BHT-4000 since the BHT-3000/BHT-4000 has no feature for regenerating those
eliminated ones automatically.
The BHT-5000/BHT-6000/BHT-6500/BHT-7000/BHT-7500 has a new feature which can handle
space characters placed in the tail of a data field as data.
The figure below shows the process in which the space characters used as padding characters
are eliminated. (Note that space characters between a and b and between b and c in field 3
are not padding characters.)
