Thanks Jim. The VB program is mine and I am writing a java app to display
some things. The java app cannot read the LAN path where the data files are
directly, but can fetch them with FTP, then read them. Dates written in the
files are the standard VB date data type. The user defined type written to
the front of the file as a header is pasted below. Offsets were calculated
and work real well for java interpretation.
