Setting Up a Transaction File 

When writing records to a Transaction File that will be submitted to the
Intrinsics, you should initialize the whole of each record to binary
zeros before setting the fields you are using.  Initialize the whole
record to zero, even those fields beyond the end of the last transaction
type you are currently using.  Doing this ensures that the files are
compatible with any changes Hewlett-Packard may introduce in later
versions of the software.  It also aids the handling of Transaction Files
in error as described below.


NOTE  There is one occasion when you shouldn't set a file to zeros before
      passing it to the Intrinsics.  This is if you use HPDNameProbe to
      validate say, the names in a Distribution List, and then supply
      this validated file to HPDUserSend or HPDGateSend.  HPDNameProbe
      puts a marker in the transaction result field to show it has been
      validated.  If you set these fields to zero, they will have to be
      validated again by HPDUserSend or HPDGateSend.
