Przemyslaw Czerpak 24f045e4e4 2006-08-10 14:00 UTC+0200 Przemyslaw Czerpak (druzus/at/priv.onet.pl) 
* harbour/include/hbapifs.h
    * changed order of members in HB_FNAME structure to avoid possible
      problems with alignment

  * harbour/include/hbexprb.c
    ! cleaned usGroups usage to avoid BCC warnings

  * harbour/source/rtl/filesys.c
  * harbour/source/rtl/fstemp.c
    * code formatting and casting

  * harbour/include/hbset.h
  * harbour/source/rtl/set.c
    * some minor updates for future incoming hb_set structure
      modifications

  * harbour/source/vm/hvm.c
    * use HB_MACRO2STRING() macro for default lang setting

  * harbour/include/hbrdddel.h
  * harbour/source/rdd/delim1.c
  * harbour/source/rdd/dbcmd.c
    + extended COPY TO ... DELIMITED ... / APPEND FROM ... DELIMITED ...
      to support some other common formats.
          COPY TO ... DELIMITED WITH TAB
          APPEND FROM ... DELIMITED WITH TAB
      uses chr(9) as field separator and without string delimiters
          COPY TO ... DELIMITED WITH PIPE
          APPEND FROM ... DELIMITED WITH PIPE
      uses '|' as field separator and without string delimiters
          COPY TO ... DELIMITED WITH ( { cStrDelim, cFldSeparator } )
          APPEND FROM ... DELIMITED WITH ( { cStrDelim, cFldSeparator } )
      allows users to set and any character field delimiters and fields
      separators
