To display the content of the Data Structure Call Definition section, you must select a Data Structure call in the left area of the tab. In the Data Structure Call Definition, you must give the Data Structure its name and location in the generated Program, as well as some physical characteristics. You must also select which of its Segments are to be taken into account. This section gives you access to the Data Structure editor tabs.
Value | Meaning |
---|---|
AA to ZZ and 0A to 0Z | These values cause the lines entered in this tab to
be generated at the beginning of the Working-Storage Section. Relatively
to the Data Structures called in the -W Lines tab, these
lines will be generated as follows:
|
00 to 09, 1A to 19... 9A to 99 | The lines entered in this tab will be generated in the Working-Storage Section, after all the Data Structures whose ' COBOL position' is lower than this prefix |
$n | This represents a parameterized value in a Macro-Structure |
It sets the sequence in which the Data Structure or Report will be processed in the Program/Macro.
When the Data Structure or Report is used only once in a Program, it is recommended to indicate the same code as the one entered as the Data Structure/Report name (chosen upon creation). However if it is called more than once in a Program, you may differentiate these calls. You can parameterize this code in a Macro-Structure with $n.
You should select the format according to the usage of the Data Structure, specified in the 'Usage definition' group of the 'Data Structure Line Definition' section, in the '-CD Lines' tab of the Program editor.
Value | Meaning |
---|---|
Redefined records | No VALUE clause is generated |
1: Records without initial values | Records without initial values or occurs. These records
are presented with the Segment common part followed by the different specific
parts. If the Data Structure description appears in the COBOL File Section, the 'Level' field must be set to 2. With this value, the specific Segments are described without redefines, at the COBOL level 02. Several Segment descriptions are grouped together under the same I/O area. |
2: Records with initial values | Records with the specific initial values indicated in the Segment -CE Lines tab. These values may also default to blank or zero depending on the format. Initial values are also generated for the occursed fields if the 'Generated language' of the Library is set to COBOL II, 85, or 370. |
3: Records with occurs (used with level 2) | Records which incorporate the occurs number indicated
in the 'Table size' field of the Segment Definition tab. No VALUE clause will be generated. If the description of the Data Structure appears in the COBOL File Section, the 'Level' field must set to 2. This type of description cannot be used if the common part Segment of this Data Structure is assigned a value in the 'Table size' field of the Segment Definition tab. (In that case, use the 'W: File description in Working' Organization and the 'T: Table stored in memory' Usage). |
4: Records with occurs (used with level 3) | Records which incorporate the occurs number indicated
in the 'Table size' field of the Segment Definition tab. The associated
'Level' field must be set to 3. A COBOL level 02 is used to access the table made up of occurs of the same record (ddssT). A COBOL level 01 is used to group the whole D.S. together - common or specific parts, whether occurred or not. A group level field that incorporates all instances is generated. This type of description cannot be used if the common part Segment of this Data Structure is assigned a value in the 'Table size' field of the Segment Definition tab. (In that case, use the 'W: File description in Working' Organization and the 'T: Table stored in memory' Usage). |
Value | Meaning |
---|---|
1: COBOL 01 level for DS area and segments | If the Data Structure description appears in the COBOL
File Section, the Segments must be redefined. If a Data Structure has no common part with a non- redefined description, the D.S. Area will only appear when the 'Generated description type' is set to 'Redefined records'. |
2: COBOL 01 level for DS area and segments at 02 level | If the 'Generated description type' is set to 'Redefined records', the D.S. Area and Segments will be described at level 02 (Preferably use a 'L: Working with placement' Organization and define the higher levels through Work Areas). |
3: COBOL level varying with records description type | Level 02 for D.S. Area & level 03 for Segments if
the 'Generated description type' is set to '1: Records without initial values',
'2: Records with initial values' or '3: Records with occurs (used with level
2)'. Level 01 for D.S. Area & level 03 for Segments if the 'Generated description type' is set to '4: Records with occurs (used with level 3)'. Level 03 for both D.S. and Segments if the 'Generated description type' is set to 'Redefined records'. |
4: COBOL 02 level for Data Elements, DS Areas and Segment levels disappear | Reserved for D.S. with an Organization set to 'L: Working
with placement' or 'W: File description in Working'. Level 02 for group Data Elements or elementary Elements that are not part of a group. Elementary Elements that are part of a group appear but the D.S. Area and Segment levels disappear. Level 01 is to be defined in the -W Lines tab. |
5: COBOL 01 level for Data Elements, DS Areas and Segment levels disappear | Reserved for D.S with an Organization set to 'L: Working
with placement' or a Usage set to 'D: Output file'. Level 01 for group Data Elements or elementary Elements that are not part of a group. Elementary elements that are part of a group appear but the D.S. Area and Segment levels disappear. |
You can choose whether the Data Structure must be generated in the Working Storage Section, or as the description of a Pactables Table.
You can also use this field to specify Database descriptions when the Database Description function is not used. These values are taken into account by application Programs.
Value | Comment |
---|---|
S: Sequential | This is the only authorized value for a Report, a Sequential file or a Sort file Data Structure. |
V: VSAM, UFAS | This is one of the two possible values for an Indexed
file Data Structure This value generates the STATUS KEY IS clause and the corresponding field is declared in the 'File Status' field of the Data Structure call Definition section of the '-CD Lines' tab (the part which can be viewed by clicking the More... button). |
I: Indexed | This is the other possible value for an Indexed file
Data Structure. This value corresponds to an indexed sequential organization (ISP for GCOS8 BCD). An ISP file coded 'LE' will be generated in three work areas: LE-FILE, LE-DATA and INVKEY. The VALUE of LE-DATA will be the external file name which must be the file code in the preceding $ DATA line. In the job control lines, the ISP lines give the physical characteristics of the file. |
G: Table description | This value generates the communication area with the Pactables access function. |
L: Working with placement | This is the only possible value for a Linkage Data Structure. File descriptions are generated in the Working Storage Section, but in a location you indicate in the 'COBOL position' field. |
W: File description in Working | This is the only possible value for a Working Storage Data Structure. File descriptions are generated in the Working Storage Section, before the 'WSS-BEGIN' constant. |
Y: Pacbench C/S | Call of the COPY clause which corresponds to the communication area between the client and the server (Pacbench C/S Business Components only). |
X: Comment | Data Structure used as a comment, not used for generation. |
2: DB2 segments or VAX/SQL | Generation-Description of a DB2 or VAX/SQL Segment. Only physical accesses are not generated. The structure of the variable indicators corresponding to the columns of the DB2 or VAX/SQL table is always generated. |
Q: DB2 or ALLBASE/SQL | Reserved for the description of SQL/DS, DB2/2 or DB2/6000 Databases (IBM), or ALLBASE/SQL Databases (HP3000), or DB2/2 or DB2/600 Databases (MICROFOCUS). |
D: DL/1, IDS I and II | Reserved for the description of Segments or records of the IMS (DL/1), IDS I or IDS II databases, in the generation of DBD, SYSGEN, schemas or application programs |
B: IDMS | |
A: ADABAS | |
T: 'TOTAL' files | |
O: ORACLE (< V6) | |
C: INTEREL RDBC or RFM | |
R: RDMS | |
4: DB2/400 | |
M: DATACOM DB | |
N: NONSTOP SQL | |
P: ORACLE V6 and V7 | |
9: INFORMIX, SYBASE, INGRES/SQL, or SQL SERVER | |
2: Data Structure for Socrate/Clio | |
F: Formal for Socrate/Clio |
A sub-schema is a group of Data Elements called in the Segment.
