/*
 * mbr_mgd77dat.c contains the functions for reading and writing
 * multibeam data in the MGD77DAT format.
 * These functions include:
 *   mbr_alm_mgd77dat	- allocate read/write memory
 *   mbr_dem_mgd77dat	- deallocate read/write memory
 *   mbr_rt_mgd77dat	- read and translate data
 *   mbr_wt_mgd77dat	- translate and write data

 * Revision 5.11  2008/01/14 17:52:34  caress
 * Fixed problem with comments that prevented proper processing.
 *
 * Revision 5.10  2005/11/05 00:48:03  caress
 * Programs changed to register arrays through mb_register_array() rather than allocating the memory directly with mb_realloc() or mb_malloc().
 *
 * Revision 5.9  2004/09/24 20:44:44  caress
 * Implemented code fixes provided by Bob Covill.
 *
 * Revision 5.8  2003/05/20 18:05:32  caress
 * Added svp_source to data source parameters.
