*
|
|
* Rev 1.11 22 Apr 1993 03:31:24 GREGG
|
|
* Third in a series of incremental changes to bring the translator in line
|
|
* with the MTF spec:
|
|
*
|
|
* - Removed all references to the DBLK element 'string_storage_offset',
|
|
* which no longer exists.
|
|
* - Check for incompatable versions of the Tape Format and OTC and deals
|
|
* with them the best it can, or reports tape as foreign if they're too
|
|
* far out. Includes ignoring the OTC and not allowing append if the
|
|
* OTC on tape is a future rev, different type, or on an alternate
|
|
* partition.
|
|
* - Updated OTC "location" attribute bits, and changed definition of
|
|
* CFIL to store stream number instead of stream ID.
|
|
*
|
|
* Matches: TFL_ERR.H 1.9, MTF10WDB.C 1.7, TRANSLAT.C 1.39, FMTINF.H 1.11,
|
|
* OTC40RD.C 1.24, MAYN40RD.C 1.56, MTF10WT.C 1.7, OTC40MSC.C 1.20
|
|
* DETFMT.C 1.13, MTF.H 1.4
|
|
*
|
|
* Rev 1.10 22 Jan 1993 13:55:30 unknown
|
|
* Add the min_size_for_tblk field that was added in rev 1.8.1.0. This revision
|
|
* should work with the rev 1.11 of the lwtfinf.c.
|
|
*
|
|
*
|
|
* Rev 1.9 30 Apr 1992 16:47:58 CHARLIE
|
|
* Eliminated MAXFORMATNAME
|
|
*
|
|
* Eliminated format_name in TFINF
|
|
*
|
|
* format_id in TFINF is a resource index specified in eng_fmt.h to allow
|
|
* the UI to control the string associated with each format
|
|
*
|
|
* Rev 1.8 31 Mar 1992 14:22:18 NED
|
|
* added indication that translators could read from VCB buffer
|
|
*
|
|
* Rev 1.7 22 Jul 1991 12:41:14 GREGG
|
|
* Added format attribute bit to indicate we must write a continuation tape if
|
|
* EOS coincides with EOM.
|
|
*
|
|
* Rev 1.6 07 Jun 1991 01:21:46 GREGG
|
|
* Changed proto from TF_GetTapeFormatIndex to TF_GetTapeFormatID
|
|
*
|
|
* Rev 1.5 06 Jun 1991 11:30:00 GREGG
|
|
* added format_id field
|
|
*
|
|
* Rev 1.4 05 Jun 1991 15:23:20 NED
|
|
* added TF_GetTapeFormatIndex() and TF_GetTapeFormatFromIndex() calls,
|
|
* TAPES_FIRST_TO_LAST attribute bit, and define for UNKNOWN_FORMAT
|
|
*
|
|
* Rev 1.3 21 May 1991 17:00:56 NED
|
|
* added max_password_size field to structure,
|
|
* moved function declarations to this module.
|
|
*
|
|
* Rev 1.2 17 May 1991 08:57:02 DAVIDH
|
|
* Cleared up errors found by Watcom compiler.
|
|
*
|
|
* Rev 1.1 10 May 1991 17:25:54 GREGG
|
|
* Ned's new stuff.
|
|
