 *   LITTLE_ENDIAN switch to little endian
 *   OPPOSITE_ENDIAN switch to opposite endian

 *   BYTE <N> inserts the given integer in [0,255] or char in 'a' format
 *   START_LENGTH <name> marks the start of a length to measure
 *   END_LENGTH <name> records the length since START_LENGTH under the given name
 *                     (or if no START_LENGTH, absolute length)
 *   LENGTH <name> inserts the saved length of the same name
 *   CHOP <N> chops last N bytes off the data
