! cleanup
* include/hbrdddel.h
* include/hbrddsdf.h
* src/rdd/delim1.c
* src/rdd/sdf1.c
+ added support for any standard EOL combination to DELIM and SDF RDDs,
Now LF, CRLF, CR and LFCR EOLs are supported and automatically
recognized during import if one of such EOLs is also set in HVM by
_SET_EOL.
% use 8192 bytes read ahead buffer to speed up import from DELIM and
SDF RDDs
+ modified file IO operations to work with stream only (no support for
file seek) Harbour File IO drivers
% optimized some File IO operations
* strip all EOF (^Z) characters from imported data. It's not strictly
Cl*pper compatible because Cl*pper interrupts import on first ^Z
character anyhow it was always the source of problems when .txt
files are concatenated by tools like 'cat' in *nixes so I decided
to change it.
+ added support RECORD clause command in commands like:
APPEND FROM "data.txt" RECORD (nRec) DELIMITED
APPEND FROM "data.txt" RECORD (nRec) SDF
It's Harbour extension - Cl*pper does not support it.
+ generate RTE when some unsupported in transfer RDDs methods are
called
