The .VAN Output File
Each time the MMI Save & Exit command is used, an output file is created on the floppy
disk. This file contains transponder information such as the meter reading, the receiver
channel activity, and the status code. This file, like the Reading.rte file, has a header
followed by a variable number of transponder records. The actual filename used for this
file is built from a combination of the route name stored in the Reading.rte file, the
system month and day, and if needed, a single letter suffix. This method of filename
creation allows for the same route to be read multiple times using the same disk, without
overwriting data from the previous route file. If the floppy disk is full when a .van file is
to be written, the MMI will prompt for a disk change. The format of the .van file is
shown below, and Figure 23 is a sample .van output file listing.

check.
