This variable allows you to adjust the case of data file names. Possible values are:
0 (default) No translation of the name is done.
1 Data file names are translated to lower case.
2 Data file names are translated to upper case.
Translation occurs before the FILE_SUFFIX and FILE_PREFIX variables are applied. Be sure that these variables specify the
correct case.
File name translation does not occur if the file name starts with -F, -D, or -P.
