 * Structure for building "argc/argv" vector of arguments.
 *
 * !!!
 * All arguments are nul terminated as well as having an associated length.
 * The argument vector is NOT necessarily NULL terminated.  The proper way
 * to check the number of arguments is to use the argc value in the EXCMDARG
 * structure or to walk the array until an ARGS structure with a length of 0
 * is found.
