Filler definition
Fillers are not defined in the repository. They can be called from Segments, but not from Tables. They are used as alignment fields, and do not contain any information. Therefore, they are characterized only by their lengths. Their length is represented by the values that are entered in the Format and Usage fields in the Filler definition section. To display the content of the Filler definition section, you must select a filler call line in the list of the called elements. In this section, you define the length of the filler for the current Segment in the Format and Usage fields. Redefines are possible for fillers.
To display the Filler definition section, select the filler call line in the -CE lines of the Segment.
- Label
- The label is optional for a filler.
- Occurs
- This field represents the OCCURS clause of an elementary Data Element, a group, or a filler. The restrictions of the COBOL OCCURS clause apply.
- Sort key
- This field identifies all the Data Elements that can be used as
control break sort keys, or as access keys to a file, a database or
a Pactables Table.Note: It is advised to dedicate a Segment to only one type of use. Each Data Element that can belong to a sort key must be referenced by a unique alphabetic or numeric character. It is advised to reference the indicators by a series (1, 2, 3 for example). The actual sort sequence is selected at the Program level (on the -CD Lines tab).You must not forget that the format of key group Data Elements must have been entered in the repository or at the Segment level.
Table 1. Possible values of the sort key for Pactables Value Comments U References the access key for a Table. This value must be indicated on the group Data Element if it is a group key. S Indicates that the Data Element belongs to at least one subsystem. Table 2. Possible values of the sort key for DL/1 databases Values Comments U References a unique key for a DL/1 database. M References a multiple key for a DL/1 database. 1 - 9 Secondary index All other values designate a search field. Table 3. Possible values of the sort key for AS400 and relational databases Values Comments 0 - 9 AS400 physical file key. relational databases V Variable length column Blank Fixed-length column W For DB2 SQL, SQL/DS and ORACLE, generation of a variable length column (VARCHAR). L For DB2 SQL, SQL/DS and ORACLE, generation of a LONG VARCHAR. Note: Sort keys are not authorized on Data Elements redefining other Data Elements.
- Format
- The format is required for a filler. It is the internal format,
defined in the same way as in the definition of a Data Element. The
input and output formats are identical, but with a DISPLAY usage.
The format and usage represent the length of the filler. There are
three categories of fillers:
- Fillers that contain alphanumeric characters. This category is also used for dates with a nonstandard format,
- Fillers that contain numeric characters only,
- Fillers for date with a standard format.
If the format of a numeric Data Element is more than 10 characters long, you must omit the 9 that would normally be entered after the V. For example, S9(10)V9(3) must be entered as S9(10)V(3). This way of coding must not be used when the format is shorter than 10 characters.
You must enter the internal format like a COBOL picture, without print characters.
The INTERNAL USAGE clause is associated with this format.
Data Elements that represent a date can be assigned a symbolic format:Table 4. Format of a filler Symbolic value Meaning D Without century (DDMMYY or MMDDYY) C With century (DDMMCCYY or MMDDCCYY) I Without century (YYMMDD) S With century (CCYYMMDD) E Without century (DD/MM/YY or MM/DD/YY) M With century (DD/MM/CCYY or MM/DD/CCYY) G Gregorian format (CCYY-MM-DD) T Timestamp format Note: For the formats that include a separator (E, G, M, and T), you can specify a separator after the character that represents the format, if you do not want to use the separator included by default in the format. For example, a G/ format generates CCYY/MM/DD instead of CCYY-MM-DD, which is the default Gregorian format.
- Usage
- It corresponds to the COBOL USAGE clause.
With the USAGE clause of a COBOL numeric variable, you indicate the internal representation of its value. Different usages are available depending on the COBOL variants adapted to the material in use.
You select a Data Element usage according to the following elements:- The type of COBOL to generate associated with the Library where you define the Data Element.
- The internal representation that you want. Example: If you generate for IBM, a C usage generates USAGE BINARY and F generates USAGE COMP-1. For UNISYS 1100, an H usage generates USAGE COMP.
Example: The DELCO Data Element is defined in the HIG Library with a C usage. You use it in a LOW Library with a type of COBOL to generate for UNISYS 1100.The Data Element usage is automatically replaced with an equivalent that is compatible with the type of COBOL to generate. So when you view DELCO in LOW, the usage that is automatically displayed is H.Table 5. Possible values for the usage Value Meaning B COMPUTATIONAL-1 ICL 1900 BINARY-1 UNISYS 1100 C COMPUTATIONAL (binary) IBM or equivalent. BINARY IBM and COBOL II variant.
D DISPLAY (default option except for Unicode-type Data Elements). Required for date Data Elements.

H COMPUTATIONAL UNISYS 2200. BINARY UNISYS 2200 (COBOL 85).
I DISPLAY-1 UNISYS 2200. J COMPUTATIONAL-6 GCOS8. REAL UNISYS-A.
N COMPUTATIONAL-4 aligned on a half-byte. You must add the complement if the length is uneven. NATIONAL (default usage) for Unicode-type Data Elements (U type).
O COMPUTATIONAL-4 UNISYS 2200 P COMPUTATIONAL-1 GCOS8. Q COMPUTATIONAL GCOS8. R COMPUTATIONAL SYNCHRONIZED RIGHT, IBM or equivalent. This value is preferable to C when binary data is aligned on even addresses, because the corresponding COBOL statements are more efficient. T COMPUTATIONAL-3 PACKED SYNC. GCOS8. U COMPUTATIONAL-1 UNISYS 2200. W COMPUTATIONAL-2 UNISYS 2200. COMPUTATIONAL-12 GCOS8.
Relational database: floating point, double precision.

Y DB-KEY GCOS8. POINTER IBM and MICRO FOCUS Z In batch mode only: this option, which is only used with an output format, generates a BLANK WHEN ZERO clause with the Batch Applications function. 0 COMPUTATIONAL-7 GCOS8 1 DISPLAY SIGN LEADING SEPARATE for UNISYS 2200, GCOS8, IBM, TANDEM, GCOS7. NATIONAL SIGN IS LEADING SEPARATE CHARACTER for Unicode-type Data Elements (U type).

- Redefines
- The Data Element that contains this option redefines the Data Element of the same COBOL level that precedes it in the Segment description. If a Data Element that redefines another Data Element is contained in a group, it is considered to be an elementary Data Element. It must be taken into account in the calculation of the number of Data Elements that are contained in a group (except for DL/1 database Segments).
