/*
 * This program generates a binary file of 256 bytes, containing every
 * possible octet value in linearly increasing order.  The purpose of this
 * datum is testing of A-linear-A and mu-linear-mu PCM conversions: we need
 * to ensure that each of those sequences is an identity transform for all
 * possible PCM octet values.
