***** End V7 Development *****
2043 TJK 24-Feb-84
Have OPEN and CLOSE recognize the LIMIT= keyword once again.
This keyword takes an integer expression. Entries were added
to the tables OPNKWD and IOCKVEC in OPENCLOSE, and KEYWFLAG in
CFCHECK. LIMIT= is illegal for INQUIRE and is flagged as both
an ANSI and a VAX incompatibility. Note that this edit was
somewhat different for V7A and V10. Among other things, V7A
didn't have to change TABLES but V10 did.
***** Begin Version 10 *****
2200 TFV 17-Mar-83
Implement INQUIRE. Merge it with OPENCLOSE. All INQUIRE
keyword values are modified by the statement except ERR, FILE,
and UNIT. Only IOSTAT and ASSOCIATEVARIABLE are modified by
OPEN and CLOSE. Give a warning for probable user error of
character constant where numeric expression is required. I.e.
RECL='40' is treated as RECL=28118614016.
2247 AlB 22-Dec-83
Add Compatibility Flagging for BACKFILE statement.
Routine:
BKSPST
2252 AlB 27-Dec-83
Change edit 2247 to use ISN instead of LEXLINE for line number.
Add compatibility flagging for FIND statement.
Routines:
BKSPST, FINDSTA
2274 AlB 24-Jan-84
Added compatibility flagging for OPEN/CLOSE keywords.
Added CFCHECK and CFSEARCH routines.
CARRIAGECONTROL keyword now accepted by the INQUIRE statement.
Routines:
CFCHECK CFSEARCH OPENCLOSE
2316 AlB 27-Feb-84
Changes made in order that this module more nearly conform
to programming conventions. The only change in functionality
is to CFCHECK, which no longer returns a value.
2370 MEM 5-Jun-84
Changes were made so that specifiers more than 6 characters could be
recognized past the sixth character in open/close statements. The
contents of the five tables OPNKWD, IOCKVAL, INQUVAL, IOCKCODE and
KEYWFLAG are combined and stored in the macro THEKEYS. Previously,
IOCKVAL, INQUVAL and IOCKCODE had been stored in one table called
IOCKEYVEC.
2413 MEM 5-Jul-84
Add the keyword TAPEFORMAT.
2424 MEM 10-Jul-84
Add the keyword DIALOGUE and correct the error message for putting a
READONLY keyword in an inquire statement. Previously it gave
'Found ")" when expecting keyword', and now it gives 'Unrecognized
keyword READONLY'. Error messages E300 and E182 were corrected also.
2426 MEM 16-Jul-84
Don't allow a specifier to occur multiple times with different
spellings in the same open/close/inquire statement. Fix broken
DIALOG by placing DIALOG(without =) at end of table.
2455 MEM 30-Aug-84
Replace all occurrences of VAX with VMS.
2461 CDM 28-Sep-84
Add octal and hexadecimal constants for the Military Standard
MIL-STD-1753 to DATA statements.
2467 RVM 17-Oct-84
Add the OPEN/CLOSE keyword DISP= (a VAX synonym for DISPOSE=).
2476 MEM 7-Nov-84
Fix index number into THEKEYS for DIALOGUE and READONLY so
compatability message has full specifier in it instead of the
abbreviated 6 character specifier.
2477 AlB 15-Nov-84
Use the global flagger prefixes in CFCHECK.
2503 MEM 27-Nov-84
Fix index number into THEKEYS for ASSOCIATEVARIABLE, CARRAIGECONTROL,
and DISPOSE.
2511 MEM 7-Jan-85
Fixed a couple of error messages in OPENCLOSE which were passing an
ascii argument when a sixbit argument was expected. Changed an entry
in THEKEYS to make RECORDTYPE legal in an inquire statement.
2523 MEM 11-Mar-85
Separate open and close keyword specifiers.

! THEKEYS is a macro which contains the contents of the tables OPNKWD,
! IOCKVAL, OPNCKVAL, IOCKCODE, and KEYWFLAG. These five tables are each
! expanded separately. Since all five of these tables must match,
! combining them together simplifies the task of adding to these tables
! at a later date. The tables OPNKWD, IOCKVAL, OPNCKVAL and IOCKCODE are
