| 1. Alternate
Characters |
| Data for which a code conversion error has occurred in the
Record Format View or Table Format View is displayed using the following alternate
characters: |
| - Alphanumeric Item : "_" (underscore) |
|
| 2. About the editing operation |
| - For the Record Format View, the Table Format View or
when Edit of hexadecimal edit screen is performed, the cursor
position is displayed. When you select a range of characters in a character string,
the cursor position is displayed at the beginning of the range. |
| - When the length of an item exceeds the number of dislplay columns, the part that
exceeds the display columns is shown on a new line.
When this occurs, the cursor is positioned at the left side of the new line.
|
|
| 3. Indexed
Organization File |
| - For an indexed file in which duplicate prime
keys are allowed, storage order range extraction cannot be selected. |
| - Up to four alternate keys may be defined when created. |
| - The number of items that can be specified as keys when
created conforms to the
definitions in the Key Information
Setting screen (less than 255 characters). |
| - If keys are allocated to signed numeric items, the records
are in the order of absolute values. |
| - If a record format is changed and key items have
non-matching relative positions and data lengths, a malfunction will occur.
The same rule applies if an item containing a key is changed using the
Select Items function. |
| - You cannot edit the data of key items in indexed organization files using the
Hexadecimal Edit bar. |
|
| 4. When the code
system of the line sequential organization treats the data file of Unicode |
| When a line sequential file contains Unicode:
|
| - All item attributes must be National characters when treated as UCS2
code. |
| - All item attributes must be other than National characters when treated as UTF8 code. |
|
5. Environment Settings
Information file folder, work file folder, and backup file folder: |
| - Do not specify the root drive. Specify a subfolder. |
| - Use a file system that supports long
file names. |
| - Use an absolute pathname, not a relative pathname, for the specification. |
|
| 6. Undo |
| - Undo is disabled when another record is displayed or when a menu item is being
executed. |
| - Undo is disabled if no data has been changed. |
|
| 7. Changing the Font |
| - A character size from 6 through 26 can be set. |
| - The font color setting in the View > Font dialog box is ignored. |
|
| 8. Hexadecimal Edit |
| - An item with the BIT attribute cannot be handled. |
| - The value may shift by the Limit of the
SYSTEM for items that exceed 2000 bytes. |
| - The Cursor Placement on the Hexadecimal Edit Bar is displayed by
the form of "Current position/Attribute length" (The Unit of Measure: Byte Count). |
| 10. Search |
A code conversion error occurs with the data when the code system of
the data file is EBCDIC, and Unicode is not correctly retrieved.
The following data items cannot be handled: |
| - Floating-point item (COMP-1, COMP-2, external floating-point item) |
| - Internal Boolean item (BIT) |
| The following character cannot be specified in search character
strings: |
| - "_" (Underscore) |
|
| If the COPY clause and a data file have different record lengths, the
following applies. The same rule also applies to the variable length record format. |
| If COPY clause record length < Data file record length |
The user cannot specify a data item corresponding to a relative
position exceeding the data file record length (not displayed in the
list of the Select Items dialog box). |
| If COPY clause record length < Data file record length |
The user cannot search the portion of data exceeding the COPY clause
record length. |
|
|
| 11. Search for Hexadecimal Data |
|
| Matching data that extends over two or more data items is not assumed to
be a match. |
| The following data item cannot be handled: |
| - Internal Boolean item (BIT) |
|
|
The following describes the specification used if the COPY clause and a data
file have different record lengths. The same rule also applies to the variable
length record format. |
| If COPY clause record length > Data file record length: |
The user cannot specify a data item corresponding to a relative
position exceeding the data file record length (not displayed in the
list of the Select Items dialog box). |
| If COPY clause record length < Data file record length: |
The user cannot search the portion of data exceeding the COPY clause
record length. |
|
|
| 12. Search, Search for Hexadecimal
Data and Previous and Next |
|
|
The cursor is placed in a matching data item. Thus, the cursor is
placed only once in a data item even though the data item contains multiple
matching character strings and values. |
|
| 13. Search Item Name |
|
|
The following describes the specification used if the COPY clause and a data
file have different record lengths. The same rule also applies to the variable
length record format. |
| If COPY clause record length > Data file record length: |
The user cannot specify a data item corresponding to a relative
position exceeding the data file record length (not displayed in the
list of the Select Items dialog box). |
|
|
| 14. Extraction by specification of
data condition |
|
| Up to ten data extraction conditions can be specified. |
| The items which cannot be specified for the data condition are:
|
| - Floating-point item |
| - Internal Boolean item (BIT) |
| - External Boolean item |
| - Item not selected by Select Items (group item when Select Items is
default) |
| - When the record length of the data file is longer than the record length
of the format, an item located in the area where the record length of the data file is
exceeded. |
|
| When the access method is a binary access, the data condition cannot be
extracted. |
|
| 15. Data Generation/Generat Item Values |
|
| - The number of characters that can be specified for the format is 128
bytes or less. |
| - The number of characters that can be specified for a start value and
an end value is 128 bytes or less, including the comma. etc. |
| - The range of values that can be specified for an increment value
is "-9" to "+9".
|
| - Up to five digits can be specified for format %s and %S. |
| - Up to 18 digits can be specified for format %D and %U.
|
| - Up to 3 fixed parts can be specified for an alphanumeric character. The limitation
is not in the variable part. |
| - For each format definition, only one fixed part and one variable part can be specified.
|
| - Up to 100 formats can be specified. |
|
| The items which cannot be processed by Data Generation/Generate Item Values are the following: |
| - Pointer item |
| - Floating-point item |
| - Boolean item |
| - N item |
| - Relative record number of relative organization |
| - Item not selected by Select Items (Group item when Select Items is
default) |
| - When the record length of the format is longer than the record length of
the data file, an item located in the area where the record length of the data file is
exceeded. |
|
| 16. Table Format View |
|
To confirm a value entered in an item, move the cursor or
press the Enter key.
Performing any other processing before confirming your input
discards the input data. |
|
| 17. Replace |
| The limitation and precautions concerning the retrieval apply
correspondingly to "10. Search". |
|
| - The length of the retrieval character and the replacement character is
assumed to be the same. It is an error for "Retrieval Character" < "Replace
Character", or "Retrieval Character" > "Replace Character" |
| - When the retrieval substitution for the character string is executed,
check the attribute of the item of the retrieval character string and the
replacement character string. |
| - The Replacement processing of the key item of an indexed or relative organization is not done. |
| - The replace function only works for data of X items (alphanumeric characters) or N items (national characters). |
|
| 18. Replace the hexadecimal data |
| The limitation and precautions concerning the retrieval apply
correspondingly to "11. Search for Hexadecimal Data". |
|
| - The length of the retrieval character and the replacement character is
assumed to be the same. It is an error for Retrieval Character < Replace Character, or
Retrieval Character > Replace Character. |
| - When the hexadecimal retrieval replacement is executed, if the input
data causes a code conversion error by the replacement character string,
it will not be done because of the error. |
| - The Replacement processing to the key item of an indexed or relative organization is not done. |
| - The replace function only works for data of X items (alphanumeric characters) or N items (national characters). |
