3   Illegal keyword.
Recognized keywords are:

  DATABASE, PREDICATES, DOMAINS, CLAUSES,
  GOAL, GLOBAL, INCLUDE, CONSTANTS

and the options are:

  check_determ, nobreak, nowarnings, diagnostics
  trace, shorttrace, code, trail, errorlevel, project
#
4   Use the format CODE=dddd, HEAP=dddd or ERRORLEVEL=d.
 Ex.
  code=4000  heap=6000  errorlevel=1
#
6   The code size in DOS cannot exceed 16000 paragraphs (corresponding to 256K).
#
7   The errorlevel must be either 0, 1 or 2.
#
10  Illegal character.
Legal characters are upper and lower case letters, digits and the
characters :-+!"'/*()[]|><=.,;
#
11  Character constants must be terminated with an apostrophe (')
Eg 'a' and '\254'
#
12  The comment is not terminated by */
End of source has been encountered within a comment. This may be
caused by nested comments.
#
14  The name is too long. (max. 250 characters)
#
15  The string is too long. (max. 250 characters in the source text)
#
16  The string must be terminated with a double quote (") in the same line.
If you need newline characters in a string, use \n as in "First\n Next".
If you need a string with more than 250 characters, use 'concat' to
assemble it from shorter strings.
#
17  Real constant is out of range.
The valid range is: +-17976931348E+-308
#
18  A hexadecimal digit is expected after a dollar sign.
Eg X=$B800
#
20  Constant identifier expected.
An 'ifdef' or an 'ifndef' should be followed by the controlling constant
identifier.
#
21  'enddef' expected; unterminated 'ifdef' or 'ifndef' block.
#
22  End of text in an unterminated ifdef-block.
#
23  Too many nested conditional blocks.
#
24  Recursion in constant definition.
#
31  The values in a binary must be in the range 0 .. 255
#
32  Syntax error in a binarry.  Example:  $[ 23, 'a', 0x56 ]
The value in a binarry must be initialized to a constant value,
variables can not be used.
#
100 Undeclared domain or misspelling.
#
102 Standard domains cannot be declared.
The standard domains are always considered to be declared, and cannot be
redeclared even if they aren't used in the program.
#
103 This domain was declared previously.
#
104 Syntax error:  =  or  ,  expected.
#
105 Name expected (either a domain or a functor).
#
106 Alternatives in a list declaration are illegal.
The only format for a list declaration is

  dom1, dom2, dom3 = otherdom*

However, there's nothing preventing 'otherdom' from being a compound
domain including different types, surrounded by functors of your
choice, as in eg.

  otherdom = i(integer); s(string); r(real)
#
107 This functor has already been used in the domain declaration.
A functor can only appear once in every domain declaration.
#
108 Functor name expected.
After the ';' a new functor name is expected.
#
109 Domain name expected.
#
110 Syntax error in domain declaration.  )  or  ,  expected.
#
111 WARNING: Domain used as a functor. (F10=Ok, Esc=Abort).
This name is also the name of a domain. If this isn't a mistake, you
can avoid the warning by succeeding the functor with two brackets as
in 'integer()'.
#
112 WARNING: Domain declaration with a single functor. (F10=Ok, Esc=Abort).
This declaration is understood as a domain with just a single functor,
which is rarely used.
#
113 This constant is already defined.
#
114 byte/word/dword expected
#
115 There must be at least one argument in a functorless domain.
#
201 This name is reserved for a standard predicate. (on selected platform)
It is not possible to redefine standard predicates.
#
202 This predicate is already declared.
Alternative declarations for the same predicate should be grouped.
#
204 Domain name  or  ')'  expected.
#
205 Undeclared domain or misspelling.
#
206 Too many arguments used in this predicate.
#
208 Syntax error in predicate declaration,  ')'  or  ',' expected.
#
209 Illegal number of arguments.
There is no declaration for the predicate with this number of arguments.
#
210 Only one database predicate declaration is allowed.
Database predicates can only have one type declaration.  If you
want to assert different types, you should use different predicates or
declare a suitable compound domain.
#
211 This predicate is declared as a database predicate.
Predicates declared in the DATABASE section must consist entirely of
facts, without using variables.
#
220 Syntax error in declaration of global predicate, '-' expected.
All global predicates must be followed by one or more flow pattern
specifications, as in
 GLOBAL PREDICATES
   determ status_RS232(integer,integer) - (i,o),(o,i) language c
#
221 Syntax error, '(' expected.
The flow pattern declaration should follow the syntax indicated in the
example below:
 GLOBAL PREDICATES
   determ status_RS232(integer,integer) - (i,o),(o,i) language c
#
222 Syntax error in flow pattern, 'i' or 'o' expected.
The flow pattern for each argument should be indicated by an 'i' for
input flow or an 'o' for output flow, as illustrated below:
 GLOBAL PREDICATES
   determ status_RS232(integer,integer) - (i,o),(o,i) language c
#
223 Wrong number of arguments in flow pattern.
All the alternative flow patterns must have the same number of
arguments as the type declaration for the predicate.
#
224 Syntax error in declaration of global predicate, 'as "NewName"' expected.
The syntax for explicitly naming an external routine is suggested below:

   determ routine(integer) - (i) language c as "MyRoutine"

Don't forget the double quotes around the name.
#
225 Compound flowpattern does not correspond to the argument domain.
#
226 Syntax error, 'PREDICATES', 'DOMAINS' or 'DATABASE' expected.
The keyword 'GLOBAL' must be followed by the name of the section you
want to declare as global.
#
227 Name of project or configuration file expected.
The directives 'project' and 'config' must be followed by a file name, eg.

  project "parser"
  config "myconfig.cfg"

A configuration file is created by the 'Save configuration' under
the 'Setup'-option.
#
228 At most one internal goal may be specified.
A 'GOAL' section has already been encountered. If there isn't one in
this file, it may have come from an included file.
#
229 The include file does not exist in the specified directory.
If the file really does exist you probably fell foul to a very common
omission, namely to use double backslashes to override the escape-function
of backslashes in strings:

  include "\\tools\\tpreds.pro"

You should also check your include directory setting.
#
230 Include files may not be used recursively.
This include file is already included.
#
231 Too many include files.
#
232 The include file is too big.
#
233 Global declarations cannot succeed local declarations.
All global declarations must be done before any local declarations.
A predicate, clause or domain section which is not preceded by the
keyword 'GLOBAL' is considered a local declaration, and cannot be
succeeded by any global declarations.
#
234 No modules in the project contains a GOAL.
#
235 The FILE domain cannot be a local domain in a project.
Simply declare the domain in a global section.
#
236 The unnamed database must be global in a project.
Simply declare the database as 'GLOBAL'.
#
237 Name of include-file expected.
#
238 Illegal declaration of file- or db_selector domain.
#
240 Identifier expected.
The syntax is: "predname : domain_with_procedure_declaration"
#
241 There can only be one fact for a predicate declared as determ.
#
401 No clauses for this predicate.
The predicate has been declared, but there are no corresponding clauses.

If this file is part of a project, note that it is possible to test
project modules interactively, but you must not refer to any of the
global predicates whose clauses are defined in other modules.
#
402 Syntax error, ',' or '.' expected in clause body.
#
403 Predicate name or section keyword expected.
#
404 Undeclared predicate, misspelling or not supported on chosen platform.
#
405 '('  expected.
#
406 ')' or ',' expected.
#
407 Illegal number of arguments: refer to declaration.
#
408 Number expected after '+' or '-'.
#
409 Syntax error.
#
410 Variable expected.
#
411 ',' expected.
#
413 Syntax error, ',' '|' or ']' expected.
#
414 Constant or variable expected.
#
415 Clauses for the same predicate should be grouped.
Clauses for this predicate have already appeared elsewhere.
#
416 Comparison operator expected i.e. one of  =   <   <=   >=   ><   <>.
#
417 Text after '.' is illegal here.
#
418 Unexpected end of text.
#
419 Syntax error in clause body, predicate call expected.
#
420 WARNING: Unused variable. (F10=Ok, Esc=abort).
If the variable does only occur once, you should instead use an
underbar. You can turn this warning off by using the 'nowarning' option.
#
422 '.' ':-' or expected.
#
423 ',' or ')' expected.
#
425 Lists should be terminated by ']'.
#
426 Initializing the global database is not allowed in a sub module.
It is only allowed to define facts for a database that is declared in
the same module. This means that all global database facts must be
initialized in the main module.

The distinction between a main module and a sub module is only that the
main module contains a goal.  If this error occurred in the main module,
it is therefore caused by an attempt to initialize the database before
the goal has been defined, in which case the compiler is still unaware
that it is the main module.  To rectify, simply move the goal to a
position before the initialization of the database.
#
427 To generate an object module the program must contain a goal.
If you want to compile a single module to an OBJ file, the module
must either contain a goal or be part of a project.
#
428 The free variable in 'findall' can only be used inside 'findall'.
#
429 The free variable in 'findall' does not occur in the predicate.
An example of use of 'findall' is:
  findall(NAME,person(NAME,_,_),L),
#
430 Language name expected.
After the 'language' directive, the name of the language must be
specified, as indicated below:
 GLOBAL PREDICATES
   determ status_RS232(integer,integer) - (i,o),(o,i) language c
#
431 Unknown language. Must be one of: pascal, fortran, c, asm.
#
432 Database name expected.
To give a database a name the 'DATABASE' keyword should be followed
by a hyphen and the name, as indicated below:

 DATABASE - lineinp
   insmode
   lineinpstate(string,col)
   lineinpflag
#
433 The domain is already defined.
A database declaration automatically generates a corresponding domain
declaration ('dbasedom' for the global database), where the name of the
domain is the name of the database.
It is not allowed to declare a database with the same name as a
previously declared domain.
#
434 The database is already declared.
The main (global) database is already declared. In order to declare a
new (local) database, you must give it a name, eg:

 DATABASE - lineinp
   insmode
   lineinpstate(string,col)
   lineinpflag
#
435 This must be the first occurrence of the Errorcode variable.
The Errorcode variable is neither allowed to be bound before the 'trap'
predicate nor can it be an output argument of the controlled predicate.
The first occurrence of the variable must be as the return variable
for the error-code, inside the 'trap' predicate.
#
436 Predicate with return value expected
#
450 Syntax error, keyword expected.
#
500 Type error.
#
501 Free variable in expression.
This is the first occurrence of the variable.
#
504 This is the first occurrence of this variable.
'bound' cannot return a bound variable. Use instead the equal sign
to bind the variable to a constant.
#
505 Type error: Illegal variable type for this position.
The type associated with the variable does not match with any of
the type declarations for the predicate.
#
506 Type error: The functor does not belong to the domain.
#
507 Type error: Wrong number of arguments.
#
508 Expressions may not contain objects of this type.
#
509 Comparisons may only be made between the basic types.
#
510 Objects from these domains cannot be compared.
#
511 There is no corresponding list domain.
To use 'findall', a suitable list domain must be declared in
the domain section.
#
512 Type error: Wrong object type.
#
513 Type error: This argument can't be a real.
In DIV and MOD, both the arguments must be integer values.
#
590 WARNING: nondeterministic clause. ( F10=Ok, Esc=abort ).
There is one or more clauses with the same entry conditions (matching
argument lists or no arguments at all) as this clause, and possible
backtracking will lead to new solutions as the clause doesn't
contain a cut.

Use 'nondeterm' before the predicate declaration if it's supposed to be
nondeterministic.
#
591 WARNING: nondeterministic predicate. ( F10=Ok, Esc=abort ).
The predicate indicated is nondeterministic, ie it may succeed again
if backtracking occurs.  This will be reflected in the calling
predicate, which also becomes nondeterministic.
Note that database predicates are, by their nature, nondeterministic;
this will therefore also apply to all uses of 'retract'.

Use nondeterm before the predicate declaration if it is OK.
#
592 ERROR nondeterministic clause in deterministic global predicate.
There is one or more clauses with the same entry conditions (matching
argument lists or no arguments at all) as this clause, and possible
backtracking will lead to new solutions as the clause doesn't

nondeterministic.
#
593 ERROR nondeterministic predicate call in deterministic global predicate.
The predicate indicated is nondeterministic, ie it may succeed again

#
600 Too many domain names.
Split the program into separate modules with local domain declarations.
#
601 Too many alternatives in the domain declaration.
#
602 Too many predicate names.
This includes both predicate and database declarations, and the
different flow pattern variants for each predicate.
Split the module into two or more sub-modules.
#
603 Too many variables in this clause.
Split the clause into two or more separate clauses.
#
604 Too many predicate calls in this clause.
Split the clause into two or more separate clauses.
#
605 Too many clauses.
Split the predicate into two or more predicates.
#
606 Too many arguments.
Combine some of the arguments with functors from a suitable domain.
#
607 Too many domain names on the left hand side of a domain declaration.
#
608 Too many database predicates.
If you  need more than this, declare some of the predicates in one or
more local databases.
#
609 Too many symbols; there can only be 64K of symbols during compilation
#
610 Code array too small.
Use code=size to get more space.
#
612 Overflow: too many structures in clause.
Split the clause into two or more clauses.
#
614 Overflow in generation of OBJ module.
Split the module into two or more separately compiled modules.
#
620 Error reading symbol table.
Something is wrong with the file <projectname>.SYM
Recompile the module(s) or project.
#
701 Loop in the flow analysis. Don't use a compound flow pattern here.
The problem is that the compiler has gone into a loop where it
continues to generate new flow variants with more and more complex
flow patterns.

If it is not an error in the program, replace the argument with a
variable and do the unification before or after the predicate call,
whatever is the appropriate.
#
703 This flow pattern doesn't exist.
You  have tried to call a standard or a global predicate with a flow
pattern which isn't recognized, either because it doesn't exist, in the
case of a standard predicate, or, in the case of a global predicate,
because it isn't declared.
The error may be caused from a higher level, where a variable which
was meant as an input argument is used as an output argument, perhaps
with an underscore.  In this case you must try to follow the calls
backward.
#
704 Free variable are not allowed in 'not' or 'retractall'.
It is not possible to get a variable bound in a 'not' or a 'retractall'
call, so you must use underscores for all unknown arguments.
#
705 Free variables are not allowed here.
'assert', 'writef' and 'format' etc. requires that all variables are
bound before the call. (Only 'write' will display a free variable as an
underscore).
#
706 The list variable in 'findall' must be free.
If it is necessary to compare the result of a call to 'findall' with
an existing list, call 'findall' with a free variable and do the
comparison after the call, as in

  findall(X,p(X),Lnew), L=Lnew,
#
707 Free variable in expression.
Arithmetic expressions cannot be evaluated if they contain free
variables.
#
708 WARNING: The variable is not bound in this clause. (F10=ok, Esc=abort)
When an output variable is not bound in a clause, it will be bound
to a free reference variable. This requires that the whole domain
to which the variable belongs is handled as a reference domain.
Avoid this if there is no need for it, as the use of reference
variables generates more code.
#
709 WARNING: Two free variables in expression. (F10=ok, Esc=abort)
This will cause the two variables to be bound to the same free
reference variable.
Avoid this if there is no need for it, as the use of reference
variables generates more code.
#
710 WARNING: Variable used twice with output flow pattern. (F10=ok,Esc=abort)
The variable is used twice as an output variable in a predicate call.
This will cause the variable to be bound to a free reference variable
before the call is done, and both arguments where the variable is used
will become input arguments (with a reference variable).
Avoid this if there is no need for it, as the use of reference
variables generates more code.
#
711 WARNING: This will create a free variable.  ( F10=Ok, Esc=abort ).
Using the first occurrence of a variable as an argument to 'free' will
cause the variable to be bound to a free reference variable.
This can be used to generate less flow variants, but will force the
domain to which the variable belongs to become a reference domain.
Avoid this if there is no need for it, as the use of reference
variables generates more code.
#
712 The variable is not bound in this clause.
When an output variable is not bound in a clause, it will be bound
to a free reference variable.
In a project all reference domains must be declared; the compiler
cannot automatically generate these when needed, as a project will
typically consist of several modules compiled from time to time.
To rectify, either rewrite the code so as to avoid the use of reference
variables or declare a reference domain for the variable.
The latter should be avoided if there is no need for it, as the use of
reference variables generates more code.

#
714 Variable used twice with output flow pattern.
The variable is used twice as an output variable in a predicate call.
This will cause the variable to be bound to a free reference variable
before the call is done, and both arguments where the variable is used
will become input arguments (with a reference variable).
However, in a project all reference domains must be declared; the
compiler cannot automatically generate these when needed, as a project
will typically consist of several modules compiled from time to time.
To rectify, either rewrite the code so as to avoid the use of reference
variables or declare a reference domain for the variables.
The latter should be avoided if there is no need for it, as the use of
reference variables generates more code.
#
715 This will create a free variable.
Using the first occurrence of a variable as an argument to 'free' will
cause the variable to be bound to a free reference variable.
This can be used to generate less flow variants, but will force the
domain to which the variable belongs to become a reference domain.
However, in a project all reference domains must be declared; the
compiler cannot automatically generate these when needed, as a project
will typically consist of several modules compiled from time to time.
To rectify, either rewrite the code so as to avoid the use of reference
variables or declare a reference domain for the variables.
The latter should be avoided if there is no need for it, as the use of
reference variables generates more code.
#
716 This argument can only be an input argument.
Look in the manual for the flowpatterns of the predicate!.
#
717 This argument can only be an output argument.
Look in the manual for the flowpatterns of the predicate!.
#
718 The domain refers to global non-reference domains.
When a domain becomes a reference domain, all underlying domains
must also be reference domains. When a local domain in a project
is declared as a reference domain, it must therefore not refer to
any global non-reference domains.
#
719 Reference to a domain, which may not become a reference domain.
When a domain becomes a reference domain, all underlying domains also
becomes reference domains.  However, functorless domains and the
standard domains FILE, DB_SELECTOR, BT_SELECTOR, REG, BGI_ILIST and
PLACE can for technical reasons not become reference domains.
#
720 Nondeterministic functions not allowed in expressions.
#
901 Domain alternative to big max size is 255 bytes.
One of the alternatives in the domain has too many arguments, so
the total size of the alternative exceeds 255 bytes.
#
902 Procedure parameters requires compilation to .OBJ
#
999 Known internal error during last call optimization. (Press F1)
The cursor will point at the last call in a clauses where
  1) Reference domains are used.
  2) A variable parameter is being converted ffrom a reference domain
     to a non reference domain
  3) There exists backtrack points earlier in the clause.
To fix the problem either:
  a) Succeede the call by another call, ex. "true"
  b) Precede the call by a cut
  c) Change the domain declarations so the conversion is not needed
We will fix this problem in a comming version.
#
------------ RUNTIME ERRORS
#
1001 Gstack overflow. Not enough memory or an endless loop.
#
1002 Heap overflow. Not enough memory or an endless loop.
#
1003 Requested block is too big (max 0xFFF0 bytes).
Internal error which should not be caused by pure Prolog code.
#
1004 Mismatch between freed blocks size and internal record.
Internal error which should not be caused by pure Prolog code.
#
1005 Attempt to release already released block.
Internal error which should not be caused by pure Prolog code.
#
1006 Heap signature overwritten
Internal error which should not be caused by pure Prolog code.
#
1007 Term too big.
A term, including associated pointer data, cannot exceed 64K when
entered into a database or sent across a message pipe.
#
1008 Memory initialization failure.
This indicates severe shortage of memory. The program is unable
to start execution.
#
1009 General protection fault
This is caused by trying to access an invalid pointer. This can
come from either a bug in some C code (a BUG in PDC Prolog), but
can also be caused by a mistake in not having the same global domains
across module boundaries, or a mistake in the domain used to save and
retrieve a term in the external database system.
#
1010 Stack overflow. Re-configure with Options if necessary.
It may be a help to re-compile the program with the option
'check_determ' turned on in order to check that no unnecessary
backtrack points are stacked, as these increase stack consumption
quite considerably.
#
1020 Trail overflow. Use trail=size to get more space.
The trail is only used in connection with reference variables,
where a free variable with input flowpattern is matched with
a constant or another variable with input flowpattern.

However, the used part of the trail can only be recovered when a
predicate fails and backtracks over the point where the trail was used.
Therefore, if the problem persists in spite of increases in the trail
size, it is necessary to change the execution sequence to avoid the
excessive trail usage. This may often be the case if a top-level predicate
uses infinite recursion ('run:- process, run.') rather than a repeat-fail
combination.

It might also help to try to cut away unneeded backtrackpoints.
#
1030 Arithmetic overflow in real operation.
The range for reals is  -1.0e308 .. 1.0e308.
#
1031 Arithmetic overflow.
Either the result of an aritmetic operation overflows the range of
the result domain, - or the conversion between two domains does
not fit into the range of the target domain.
#
1032 Division by zero.
#
1033 Negative values cannot be arguments to 'log', 'ln' or sqrt.
#
1040 Free variables are not allowed here.
This message occurs when a variable from a reference domain is tried
to be converted to a non reference domain, while the variable is free.

During automatic type conversion, as example from integer to real
it is required that variables are bound.

'assert', 'writef' and 'format' etc. requires that all variables are
bound before the call. (Only 'write' will display a free variable as an
underscore).
#
1041 Assert to a fact declared as determ, but fact's does already exist's.
#
1045 Array index too big.
The index value is outside the currect allocates binary.
#
1046 Size bigger than 64K in makebinarry
#
------------ IO & OS errors
#
1101 Attempt to open an already open file.
Note that a symbolic file-name, declared with a file-domain,
can only be used for one file at a time.
#
1102 Attempt to assign input device to a file that is not in readmode.
It is usually caused by a bug in the program so you refer to a closed file.
#
1103 Attempt to assign output device to a file that is not in writemode.
It is usually caused by a bug in the program so you refer to a closed file.
#
1104 The file isn't open.
#
1105 Illegal mode in filemode predicate, should be 0 or 1.
'0' specifies Text mode, while '1' specifies Binary (raw) mode.
#
1106 Invalid operation on device.
#
1107 Eof can only be used during readmode.
The file might be closed.
#
1108 Illegal device or path.
#
1109 Wrong number of arguments in the format string.
#
1110 File too big, or not enough memory for file.
#
1111 Wrong number of bytes read from file.
This is either caused by a corrupt database or errors using the readblock
predicate.
#
1112 Not able to write correct number of bytes to file.
This is probably caused by a full disk.
#
1113 Invalid arguments to the 'date'-predicate.
The arguments should be three integers in the order day, month, year.
#
1114 Invalid arguments to the 'time'-predicate.
The arguments should be four integers in the order
  hours       0..24
  minutes     0..59
  seconds     0..59
  hundredths  0..99

can not be found.
#
1117 Error executing external program.
The external program might be too big to be executed from the
Prolog system or it might be an illegal EXE-file, or it remained resident.
Try to execute the external program from the DOS shell to see what happens.
#
1118 Cannot access port(s).
The port(s) cannot be reserved. Another program is probably using them.
#
1133 Incorrect operating system version.

#
1201 The arguments in 'makewindow' are illegal.
Check that
  - the window number is in the range 1 .. 127
  - StartRow+NoOfRows <= no. of rows on screen (usually 25 or 43)
  - StartCol+NoOfCols <= no. of cols on screen (usually 80 or 120)
#
1202 The cursor values are illegal.
The Row and Column must be inside the actual window.
#
1203 The window referred to does not exist.
#
1205 Maximum number of windows exceeded.
#
1206 The arguments in 'resizewindow' are illegal.
in resizewindow(StartRow,StartCol,NoOfRows,NoOfCols)
Check that
  - StartRow+NoOfRows <= no. of rows on screen (usually 25 or 43)
  - StartCol+NoOfCols <= no. of cols on screen (usually 80 or 132)
  - Both StartRow and StartCol are positive.
#
1207 Scroll predicate is not supported in graphic.
#

#
-------------------------- DB Error's
#
1301 Overflow in Expanded Memory System.
#
1302 The database is already open.
A given database selector can only be opened once.
#
1303 Invalid database file name.
#
1304 The database isn't open.
No database is currently associated with DB_SELECTOR.
#
1305 The B+TREE isn't open.
The B+TREE has been closed since the bt_selector was returned
from bt_open or bt_create.
#
1306 The B+TREE already exists.
The names for the B+TREES in a single database must be unique,
and a B+TREE with the indicated name already exists.
#
1308 The database name already exists in the specified location.
The names for databases placed in memory must be unique.
#
1309 Error reopening the database during flush operation.
'db_flush' closes and opens the file in order to flush the DOS
buffers; there is sadly no other way of guaranteeing that the
buffers really are flushed on a DOS-system.
When the database file is opened again, the same name as before
is used.  This may cause problems if the database was opened in
the current (default) directory and this has been changed since
then, as 'db_flush' will have closed it in the old directory and
tries to look for it in the new directory.
#
1310 Invalid Order value; it must be between 1 and 255.
#
1311 Invalid Key length.
The key length must be between 1 and 255.
However, it should be chosen as small as possible in order to
save space.
#
1313 Type conflict. The term in the database doesn't correspond with the domain.
Database terms must be inserted and retrieved with variables belonging
to the same domain.
#
1314 Unable to create the indicated database.
#
1315 Unable to open the indicated database in the given place.
#
1316 No EMS installed.
You can not use the option 'in_ems' in db_open and db_create if
you have no EMS card installed.
#
1317 Database marked as invalid.
Whenever a database is closed, or flushed, it is totally consistent and
marked as valid; this is reverted to invalid when it's contents are
changed. If the computer crashes with an invalid database, it isn't
subsequently safe to open and use it as if nothing has happened. In this
case you must try to write a short recovery/copy program, opening the
database with the 'openinvalid' predicate and copying the contents as far
as they go to a new database.
#
1318 Unable to delete database in the indicated place.
#
1319 Invalid database reference number.
You are probably using a database reference number for a term you have
deleted, or you have maybe two open databases and are referring to the
wrong database.
#
1320 The chain does not exist in the database.
#
1321 The named B+Tree does not exist in the database.
#
1322 Invalid B+Tree selector for the given database.
You are probably using a bt_selector for a B+Tree you have deleted, or
you have maybe two open databases and are referring to the wrong database.
#
1323 Can not delete an open index. (Close it first)
#
1324 Key and ref not found in B+tree during key_delete.
You either have a wrong combination of KEY and REF, or you are referring
to a wrong B+Tree.
#
1325 Term too big for conversion.
A single term must not occupy more than 64K for insertion in databases or
transmission on a message pipe.
#
1326 Incorrect database system version.
The database was not created with the same version of the database system
as the one you are now using.
#
1327 Not inside transaction.
The database was opened in sharemode, so all predicates that access the
database must be placed inside a transaction.
#
1328 Write transaction not allowed when file opened in readonly.
db_begintransaction was called with readwrite, but the database
was opened as readonly.
#
1330 Begintransaction made twice without endtransaction.
After a call of db_begintransaction, db_endtransaction must be called
to mark the end of the transaction before another call to db_begintransaction.
#
1331 Update of the database not allowed in readonly mode.
#
1332 Timeout in begintransaction
After having tried RetryCount times with SleepPeriod intervals,
db_begintransaction was unable to access the file.
#
1333 KEY does already exist, and duplicates are not allowed in selected B+Tree
#
1334 Wrong chain or inconsistency in database found in TERM_DELETE
#
1335 Only one database can be in_ems when using DB_LOADEMS/DB_SAVEEMS
#

#
-------------------------- Message
#
1801 Message queue memory allocation failure.
The operating system was unable to access or allocate memory
required by the message queue system.
#
1802 The pipe is closed.
The program at the other end of the pipe has closed it.
#
1803 The pipe is broken.
The pipe connection is lost and the other end didn't close the pipe normally.
This may be caused by the program at the other end of the pipe terminating
without closing the pipe, or a loss of connection somewhere in the operating
system or, in the case of a networked pipe, a network error.
#
1804 Cannot open pipe.
The pipe doesn't exist.
#
1805 Invalid pipe name.
The name must begin with \pipe\ or \\computername\pipe
