#### NAT0405: MOVE ALL with SUBSTR for target field and UNTIL value not allowed

    Text
    MOVE ALL with SUBSTR for target field and UNTIL value not allowed.
    Explanation
    When SUBSTR is applied to the target field in a MOVE ALL statement,
    the use of an UNTIL value is not permitted.
    If only a part of the target field is to be affected by the
    MOVE ALL, use the starting position and length of the SUBSTR clause
    to define the field segment to be filled with the pattern.
    Action
    Remove either the UNTIL value or the SUBSTR clause.

#### NAT0406: Explicit index range not allowed with SORT.

    Text
    Explicit index range not allowed with SORT.
    Explanation
    Only complete arrays can be specified in the USING clause of the
    SORT statement. This can be achieved by specifying "*" as index
    or by explicitly specifying the complete range of constants.
    Example:  01 ARRAY (A5/1:20)
              ...
              SORT BY ... USING ARRAY(*)    or
              SORT BY ... USING ARRAY(1:20)
    Action
    Check program and correct error.

#### NAT0407: Invalid tab notation "nT".

    Text
    Invalid tab notation "nT".
    Explanation
    The "nT" positioning must be within the useable line size.
    "n" must not be zero or a value greater than the currently
    specified line size.
    Action
    Check program and correct error.

#### NAT0408: Tab notation "nT" duplicated or invalid in VERT mode.

    Text
    Tab notation "nT" duplicated or invalid in VERT mode.
    Explanation
    The "nT" positioning can be used to position to a specific output
    position. In VERT mode, positioning can only be done once between
    two columns. It cannot be specified for individual fields in VERT
    mode, because the column position can only be defined once before
    the VERT entry.
    If indentation is required, use the "nX" notation within a column.
    Action
    Check program and correct error.

#### NAT0409: Position ref. to field only allowed once between columns.

    Text
    Position reference to field only allowed once between columns.
    Explanation
    The position reference of the form "T*NAME" can only be used to position
    to a new column in a DISPLAY statement.
    Within a column in VERT mode, it is not possible to position individual
    fields with the "T*NAME" notation.
    If indentation is required within a column, use the "nX" notation.
    Action
    Check program and correct error.

#### NAT0411: Print position reference must be in first DISPLAY.

    Text
    Print position reference must be in first DISPLAY.
    Explanation
    Only the first DISPLAY statement creates a print position reference.
    Reference to print positions (columns) in the form "T*NAME" can only
    be made to variables that have been defined as columns in the first
    DISPLAY statement defined in the program.
    The short-form notation (2 characters) for database fields is not
    permitted.
    Action
    Correct error.

#### NAT0412: "nX" or "nT" notation positions beyond line size.

    Text
    "nX" or "nT" notation positions beyond line size.
    Explanation
    The notation "nX" or "nT" resulted in an output position that lies
    beyond the currently specified line size.
    Action
    Either correct the nX/nT notation or increase line size parameter.

#### NAT0413: Module in source library does not exist for .I(name).

    Text
    Module in source library does not exist for .I(name).
    Explanation
    The source module to be copied from the source library cannot be
    located in the current library, or the entry ".I(name)" was not
    specified correctly.
    Action
    Re-issue command using correct source module name.

#### NAT0415: "T*" and "P*" notation not permitted in PRINT statement.

    Text
    "T*" and "P*" notation not permitted in PRINT statement.
    Action
    Do not use "T*" or "P*" in a PRINT statement.

#### NAT0416: "x/y" notation not permitted with PRINT statement.

    Text
    "x/y" notation not permitted with PRINT statement.
    Action
    Do not use the notation "x/y" in a PRINT statement.

    Text
    Variable index range not permitted with READ WORK FILE.
    Action
    Check program and correct error.

#### NAT0418: "RETURN" is not permitted in structured mode.

    Text
    "RETURN" is not permitted in structured mode.
    Explanation
    The RETURN statement is permitted in reporting mode only.
    In structured mode, the end of a subroutine definition
    must be indicated with the statement END-SUBROUTINE.
    Action
    Check program and correct error.

#### NAT0419: "USING" is required in structured mode.

    Text
    "USING" is required in structured mode.
    Explanation
    When the SORT statement is used in structured mode, the USING clause
    has to be used to indicate the fields which are to be written to
    intermediate storage.
    If USING KEYS is specified, all sort-key fields are written to
    intermediate storage.
    USING operand2 ...  may be used to indicate fields in addition to
    the sort-key fields which are to be written to intermediate storage.
    By default in structured mode, the fields specified in the BY clause
    are NOT written to intermediate sort storage.
    Action
    Check program and correct error.

#### NAT0422: Invalid or misplaced statement in external subroutine.

    Text
    Invalid or misplaced statement in external subroutine.
    Explanation
    An external subroutine must not contain more than one
    DEFINE SUBROUTINE statement.
    The DEFINE SUBROUTINE statement block must be closed with END-SUBROUTINE
    (or RETURN, in reporting mode).
    The only statements allowed outside the DEFINE SUBROUTINE block are
    DEFINE DATA LOCAL/GLOBAL, which must precede the DEFINE SUBROUTINE
    statement, and END at the end of the subroutine.
    Action
    Correct error in external subroutine.

#### NAT0423: Invalid GIVING LENGTH clause in READ WORK FILE statement.

    Text
    Invalid GIVING LENGTH clause in READ WORK FILE statement.
    Explanation
    Possible reasons for this error are:
    1. The keyword "LENGTH" is missing after "GIVING".
    2. The operand is either missing or defined with
       an incorrect format/length (format/length must be I4).
    Action
    Check program and correct error.

#### NAT0424: Invalid operand for PC "COMMAND" option.

    Text
    Invalid operand for PC "COMMAND" option.
    Explanation
    The operand for the COMMAND option of the
    WRITE WORK FILE/WRITE PC/DOWNLOAD statement
    must be of alphanumeric format and its length
    must not exceed 80 characters.
    Action
    Check program and correct error.

#### NAT0425: Invalid use of a qualified variable name.

    Text
    Invalid use of a qualified variable name.
    Explanation
    Qualified variable names may only be used when referencing
    data variables. They cannot be used when defining variables
    in a DEFINE DATA statement.
    Action
    Check program and correct error.

#### NAT0426: Invalid use of variable name in data structure.

    Text
    Invalid use of variable name in data structure.
    Explanation
    In the DEFINE DATA statement, a variable name was used in defining
    a data structure that currently exists. The earlier variable
    definition was not part of another data structure.
    Action
    Check program and correct error.

#### NAT0428: Invalid variable name definition in a data structure.

    Text
    Invalid variable name definition in a data structure.
    Explanation
    A variable name used in the DEFINE DATA statement already exists.
    The earlier definition of this variable name describes a data
    element that is contained within the current data structure.
    Non-unique variable names in a DEFINE DATA statement are referenced
    by qualifying the variable with the level 1 structure name.
    Therefore, two data structure variables with the same variable name
    can not co-exist if they share the same level 1 structure name. E.g.:
    1 GROUP
      2 STRUCTURE-1
        3 SAME-NAME (A1)
      2 STRUCTURE-2
        3 SAME-NAME (N7)  <== cannot be uniquely referenced.
    1 OTHER-STRUCTURE
      2 SAME-NAME (P4) <== unique reference as "OTHER-STRUCTURE.SAME-NAME"
    Action
    Check program and correct error.

#### NAT0429: Index for database array incorrectly specified.

    Text
    Index for database array incorrectly specified.
    Explanation
    When defining an array, the index specification for each
    dimension must not include a non self-defining range.
    A range which is not self-defining includes any of the
    following index specifications:
      #FIELD(#I + 1) or #FIELD(#J - 1)
      #FIELD(*)
      #FIELD(#I + #J)
    Action
    Check program and correct error.

#### NAT0431: Qualifiers must be structure names on level 1.

    Text
    Qualifiers must be structure names on level 1.
    Explanation
    To identify a variable which is defined inside a data structure, you may
    prefix the variable name with the name of the level-1 structure field,
    separated with a period. Only level-1 structure field names can be used
    as field qualifiers; fields defined on level 2 or higher are not
    permitted.
    Action
    Supply a valid qualifier field.

#### NAT0434: Qualification does not uniquely identify variable.

    Text
    Qualification does not uniquely identify variable.
    Explanation
    The qualified name list does not uniquely describe the
    current variable name.
    Action
    Check program and correct error.

#### NAT0435: Index for database array incorrectly specified.

    Text
    Index for database array incorrectly specified.
    Explanation
    The Natural Version 1.2 notation of defining an index range with
    the "-" character cannot be used to reference a database array
    which was defined using the Version 2.1 notation, that is the
    character ":". The converse is not permitted either.
    Neither is it permitted to mix the two notations when defining
    a database array.
    Neither are the index notations "I + 1" or "I - 2" etc. permitted
    when referencing a database array that was defined with the
    Version 1.2 notation.
    Action
    Check program and correct error.

#### NAT0436: The internal size of a data structure is too big.

    Text
    The internal size of a data structure is too big.
    Explanation
    The size of a data structure in the DEFINE DATA statement
    is too big.
    Action
    Reduce number of variables or number of occurrences for a variable.

#### NAT0437: Constant definition missing for current structure.

    Text
    Constant definition missing for current structure.
    Explanation
    If a variable is defined as a named constant via the keyword "CONST"
    in a DEFINE DATA statement, each elementary field of that structure
    must be defined as a constant.
    Action
    Check program and correct error.

#### NAT0438: Record length must not exceed 1073741824 bytes.

    Text
    Record length must not exceed 1073741824 bytes.
    Explanation
    The length of a record read/written with a READ/WRITE WORK FILE
    statement must not exceed 1073741824 bytes (= 1 GB).
    Action
    Check program and correct error.

#### NAT0439: Variable-length field only allowed in WRITE WORK VARIABLE.

    Text
    Variable-length field only allowed in WRITE WORK VARIABLE.
    Explanation
    Fields with variable length cannot be used in a WRITE WORK FILE
    statement without VARIABLE clause.
    Incorrect example:   WRITE WORK FILE 1 array(1:j)
    Correct example  :   WRITE WORK FILE 1 VARIABLE array(1:j)
    Action
    Check program and correct error.

#### NAT0440: DISPLAY and NEWPAGE not allowed in AT TOP/END OF PAGE.

    Text
    DISPLAY and NEWPAGE not allowed in AT TOP/END OF PAGE.
    Explanation
    A DISPLAY or a NEWPAGE statement must not be placed within
    an AT TOP OF PAGE or AT END OF PAGE statement block.
    Action
    Correct error in program.

#### NAT0441: RETURN or END-SUBROUTINE not allowed within a condition.

    Text
    RETURN or END-SUBROUTINE not allowed within a condition.
    Explanation
    A RETURN or END-SUBROUTINE statement must not be placed within
    any of the following statement blocks:
       - AT START/END OF DATA
       - AT TOP/END OF PAGE

    technical supoort and describe how the error was produced.

#### NAT0444: Logical file directive for Entire system file is not type Entire.

    Text
    Logical file directive for Entire DB system file is not type Entire.
    Explanation
    Check the logical file directives for Entire DB system files 249/250
    and the database type for the Entire DB database ID.
    The logical files describe the Entire DB cross-reference and data files
    and are defined with the NTLFILE macro in the Natural parameter module:
       - NTLFILE 249,xyz,f1 (SYS1)
       - NTLFILE 250,xyz,f2 (SYS2)
    Alternatively, the logical files can be defined with the dynamic profile
    parameter LFILE:
       - LFILE=(249,xyz,f1),LFILE=(250,xyz,f2)
    The Entire DB database ID xyz must be defined with the NTDB macro in the
    Natural parameter module as type ENTIRE:
       - NTDB ADABAS,xyz,ENTIRE
    Alternatively, you may use the dynamic profile parameter DB:
       - DB=(ADABAS,xyz,ENTIRE)
    Action
    Contact your Entire DB administrator.

#### NAT0445: C buffer being used by another application.

    Text
    C buffer being used by another application.
    Explanation
    Two applications are using the same Natural buffer.
    This error is detected on starting the second application and
    as it is desirable to protect data, the second application is
    not allowed to start.
    Action
    The problem could be resolved if the two applications were to use
    separate buffers - please contact technical support.

#### NAT0446: Statement name found in attribute expression.

    which has the same name as a Natural keyword.
    Action
    Rename the attribute.

#### NAT0447: FIND UNIQUE not allowed for Entire files.

    Text
    FIND UNIQUE not allowed for Entire files.
    Explanation
    This statement is not supported by Entire.
    Action
    Correct error in program.

#### NAT0448: C interface - get memory buffer failed.

    Text
    C interface - get memory buffer failed.
    Explanation
    When a function written in C performs a MALLOC operation to
    get a work buffer, this is supplied to it by the GETMAIN# entry
    in the environment interface NICMAIN, which in turn gets it
    from the second buffer declared in the C module header. This
    buffer has not been defined in the Natural environment.
    With Natural Expert this means that no EXRSIZE or EXCSIZE could
    be allocated.
    Action
    Check whether there is enough space for the EXRSIZE or EXCSIZE as
    defined in the Natural parameter module, or increase the buffer
    size(s).

#### NAT0449: C work buffer too small.

    Text
    C work buffer too small.
    Explanation
     CALL <module> <routine> <arguments>
      On initialization of the C work buffer, the minimum size required
      is   <size of extern/static> + 4K.
    Action
    This is an internal Natural Expert error, please contact
    technical support.
