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 trailing spaces padded in the tail of

each data field.

The BHT has a new feature which can handle trailing spaces in a data field as data.

The figure below shows the process in which the spaces used as padding characters are elim-

inated. (Note that spaces between a and b and between b and c in field 3 are not padding

characters.)
