	  compute, then converting the cob_decimal to BCD back
	* move.c (cob_move_display_to_packed, cob_move_packed_to_display),
	  coblocal.h: make functions accessible within libcob

	  refactoring, calling the new cob_add_bcd internally from
	  (cob_add, cob_sub) if all fields are BCD
	* numeric.c (cob_add_bcd, check_overflow_fix_final_sign): fix handling
	  for COB_STORE_KEEP_ON_OVERFLOW and edge-case bugs

	  simplify code, following idea by of Chuck Haatveet
	* common.c (cob_is_numeric): speedup by using new macro IS_INVALID_BCD_DATA
	  which uses the new lookup table b2i
	* common.c: new macros IS_VALID_DIGIT_DATA / IS_INVALID_DIGIT_DATA added
	  and used
	* numeric.c (cob_decimal_do_round, cob_decimal_get_field): fix
	  COB_STORE_PROHIBITED to not overwrite target data and always raise an
	  exception if rounding would be necessary

	* common.c (cob_continue_after): raise nonfatal exception
	  COB_EC_CONTINUE_LESS_THAN_ZERO for negative waits
	* common.c [TIME_T_IS_NON_ARITHMETIC]: dropped checking for this define as
	  POSIX requires time_t to be an arithmetic type
	* cconv.c (cob_load_collation): minro cleanup
	* fileio.c (EXTFH) [!COB_64_BIT_POINTER]: fix check for opcode OP_CLOSE
	* move.c (store_common_region): speedup by not re-validating data if caller
	  already provides that; adjusted callers to specify that
	* common.c (cob_sys_hosted): prefer memcmp over strncmp with known size
	* common.c (, cob_sys_hosted): handling timezone functions

	* strings.c (is_marked): check for possible/definite overlap of
	  check and marker range before checking all marker bytes in range

	* move.c, common.h: new function cob_set_llint
	* move.c (cob_set_int): use const_bin_attr instead of setting it up

2020-04-14  Ron Norman <rjn@inglenet.com>

	* fileio.c: Fixed to NOT mix I/O to FILE * via putc and 'int fd' via write
