1.0 SUMMARY
The major changes between COBOL V12B and COBOL V12C are:
Bug fixes (see sec 2.1 through 2.6).
COBOL version 12C consists of:
CBL74 version 12C(1574)
C74OTS version 12C(1141)
COBDDT version 12C(47)
ISAM version 12C(212)

DEFICIENCIES
3.0 DEFICIENCIES
3.1 Deficiencies from COBOL v12 and v12A
COPY REPLACING has some problems in that it is not possible to
replace either part of PIC xyz without replacing the whole.
i.e. REPLACING ==PIC S9(10)==
will work
but
REPLACING ==PIC== or REPLACING ==S9(10)== will not.
Note, it was never the intent (and it contravenes the ANSI
standard) for COPY REPLACING to replace part of a data-item.
REPLACING AA by BB should not turn AA-XYZ into BB-XYZ.
The LINK supplied with 7.00 for loading the monitor will not load
COBOL-74 subroutines. Use field image LINK for this case.

* NOTE *
********
We do not recommend that this change be installed unless your
installation is having problems transferring data TO an IBM
machine.
The ASCII to EBCDIC translation table was changed in version 12
(as the result of several SPRs) so that the translation of
graphics was more correct. However it is still not correct
according to IBM documentation, we are currently investigating
wha t VAX does to see if there can be a DEC to IBM standard we
can live with. However it seems that we now in some cases
generate incorrect EBCDIC characters for minus zero. The interim
solution for those who see this problem is to put the translation
t able back the way it was in version 11 knowing then that the
translation of some graphics will be wrong.

DEFICIENCIES
3.2 Deficiencies from before COBOL v12
Program ID same as filename, procedure name or data name results
in spurious error messages.
If A=B and C=D or E for subscripted A and C gives wrong code,
cause "SUBSCRIPT not POSITIVE" run time message if subscripts not
COMP or INDEX.
Error not detected.
A RESET FINAL clause is legitimate only when FINAL is given as a
control. Violation of this rule goes undiagnosed. A RESET
clause can only accompany a sum clause. A RESET clause
accompanying a source clause receives no diagnostic.
Incorrect error message.
DATA-NAME RC which is defined on last line of the working-storage
section is incorrectly diagnosed as undefined in the declaratives
area of procedure division. It is considered to be defined ok in
the report section, however.
Incorrect error message.
COBOL rules make the presence of a data-name optional in the
control footing report description provided there is no need to
reference the report group. In the case where the data-name is
present the program compiles without error. In the case where
the data name is not present the compiler seems to be disallowing
sections in the procedure division.
DBMS error handling
Errors which relate to the schema are not tabulated in the error
count, and they go only to the TTY.
If "USE AFTER ERROR PROCEDURE ON x" where x is "INPUT", "OUTPUT
or "I-O" and "USE AFTER ERROR PROCEDURE ON file-name" are both
specified, then file-name may not be OPENed for x.
User error is not diagnosed: When the value of an 88-level item
is not the correct class, and the item is subordinate to a group
item which has the clause "USAGE INDEX", the program will compile
without an error diagnostic.
