8.5.2 Case Sensitivity

FreeForm ND adheres to the following rules for case sensitivity (in applicable operating systems) when it searches for a format file for the data file datafile.ext.

• FreeForm ND preserves the case of datafile, for example, the default format file for the data file LATLON.BIN is LATLON.fmt (or LATLON.bfm).
• FreeForm ND searches for a format file with a lower case extension. That is, the format file must have its extension in lower case no matter what the case of datafile. For example, the default format file for the data file LatLon.dat is LatLon.fmt (or LatLon.afm), and TIMEDATE.fmt (or TIMEDATE.bfm) is the default format file for TIMEDATE.bin.
• In searching for a format description file of type ext.fmt, FreeForm ND preserves the case of ext. For example, for data files named lldat1.LL, lldat2.LL, and latlon3.LL, the default format description file is LL.fmt.
