Overriding Individual Segment Names

You can override an individual generated segment file name by setting an environment variable named by the generated file name of the segment (converted as described above) to the full path of the desired file name. As an example, suppose the regular name of your file is /usr1/gl.dat, and you have GL_DAT_DATA_FMT=gl%d.dat set, but you want to place the second data segment on /usr2. Setting GL1_DAT=/usr2/gl1.dat will override the originally determined name. This feature works with both methods. Using the file names generated by the default method as environment variables (converted as described above) works, too.
