|
|
*
|
|
* Equates that define the structure of Advanced Revelation's Data Dictionary
|
|
*
|
|
*
|
|
EQUATE D.E.TYPE TO 1 ;* Type of current field.
|
|
;* 'F' = Data Field
|
|
;* 'S' = Symbolic (formula in D.E.FORMULA)
|
|
;* 'G' = Group (group data in D.E.DISPLAY)
|
|
|
|
EQUATE D.E.FIELD.NO TO 2 ;* The position of the data in the record
|
|
|
|
EQUATE D.E.DISPLAY TO 3 ;* The Column Heading used by RLIST and other tools
|
|
;* For type 'G' dictionary records, this field
|
|
;* contains the group data.
|
|
|
|
EQUATE D.E.SM TO 4 ;* Single or Multivalue flag "S"ingle "M"ulti
|
|
|
|
EQUATE D.E.PART TO 5 ;* Key part. For multi-part keys, this field
|
|
;* specifies the part number (1, 2, 3, etc.)
|
|
;* For single-part key fields, this field should be 0.
|
|
|
|
EQUATE D.E.INDEX.FLAG TO 6 ;* BTREE INDEX flag (boolean value).
|
|
|
|
EQUATE D.E.CONV TO 7 ;* Contains the output conversion for data
|
|
|
|
EQUATE D.E.FORMULA TO 8 ;* If the field type = "S" then this field will contain an rbasic formula
|
|
|
|
EQUATE D.E.JUST TO 9 ;* Justification for displaying and sorting data.
|
|
;* 'L' = Left
|
|
;* 'R' = Right
|
|
;* 'C' = Centered
|
|
;* 'T' = Text
|
|
;* Text justification means no justification.
|
|
|
|
EQUATE D.E.LENGTH TO 10 ;* Display length for this field. Note that this length
|
|
;* is not necessarily the length of the data itself,
|
|
;* especially in bonded files.
|
|
|
|
EQUATE D.E.PATTERN TO 11 ;* Input validation/conversion for this field
|
|
|
|
EQUATE D.E.GENERIC.TYPE TO 12 ;* The Arev Generic Data type associated with this field
|
|
|
|
EQUATE D.E.SOURCE TO 13 ;* This field is basically reserved for backwards compatibility
|
|
;* with REV/G. Don't use it.
|
|
|
|
EQUATE D.E.DESC TO 14 ;* Description of this field. Used for documentation.
|
|
;* Can be displayed as online help using an HD code.
|
|
|
|
EQUATE D.E.FOREIGN.TYPE TO 15 ;* The data type name in the foreign environment
|
|
|
|
EQUATE D.E.FOREIGN.NAME TO 16 ;* The field name in the foreign environment
|
|
|
|
EQUATE D.E.FOREIGN.MAP TO 17 ;* For bonded files, this field uniquely specifies
|
|
;* a data mapping (that is, the algorithm used to
|
|
;* transfer data between the Advanced Revelation data type
|
|
;* and the foreign data type).
|
|
|
|
EQUATE D.E.FOREIGN.ATTR TO 18 ;* This field contains any foreign field attributes
|
|
;* that a bonded dictionary field may have, separated
|
|
;* by value marks.
|
|
|
|
EQUATE D.E.PMD TO 19 ;* This field is still being designed.
|
|
|
|
EQUATE D.E.NULL.TRUNC TO 20 ;* This field allows the user to override the bond's
|
|
;* default handling of null values for this field.
|
|
;* If the bond cannot support null values, setting the first
|
|
;* value of this field to 'Y' allows nulls to be stored
|
|
;* without an error. A 'N' or null first value allows the
|
|
;* default behaviour: if the bond cannot store nulls in this
|
|
;* field and a null is written, an I/O error will result.
|
|
;* If the first value is 'Y', the second value can be
|
|
;* used to specify what value the bond should store in
|
|
;* the field when a null is written. The bond is not
|
|
;* required to support this latter ability.
|
|
|
|
EQUATE D.E.DEPENDENT TO 21 ;* Reserved for indexing.
|
|
|
|
EQUATE D.E.XREF TO 22 ;* If non-null, then there is a cross-reference index
|
|
;* on this field. In that case, the value in D.E.XREF
|
|
;* is the name of the symbolic field that calculates the
|
|
;* cross-reference index.
|
|
|
|
EQUATE D.E.RELATIONAL TO 23 ;* If non-null, then this field is used to update a relational
|
|
;* index in another file and contains the key to a record
|
|
;* in that other file.
|
|
|
|
EQUATE D.E.RELATED TO 24 ;* For relational indexes, this field is updated to contain the
|
|
;* keys to the related records in the other file.
|
|
|
|
EQUATE D.E.PROTECT TO 25 ;* 1 if this field is protected. This flag is set by
|
|
;* relational indexing process.
|
|
|
|
EQUATE D.E.LOWERCASE TO 26 ;* Controls how indexed fields are indexed:
|
|
;* 0 = convert to uppercase
|
|
;* 1 = maintain case supplied.
|
|
|
|
EQUATE D.E.COMPUTED TO 27 ;* Reserved for indexing.
|
|
|
|
EQUATE D.E.MASTER.FLAG TO 28 ;* For 'F'-type dictionary records, this flag
|
|
;* distinguishes synonym fields from the "real" field.
|
|
;* This flag is '0' for synonyms and '1' otherwise.
|
|
|
|
EQUATE D.E.DEFAULT TO 29 ;* SQL default value for insertions.
|
|
|
|
EQUATE D.E.REFERENCE TO 30 ;* SQL. Indicates this column is a foreign key to the listed table(s).
|
|
|
|
EQUATE D.E.NULL TO 31 ;* SQL.
|
|
;* 0 = column can store nulls.
|
|
;* 1 = column can't store nulls.
|
|
;* We're still figuring out whether this field and
|
|
;* D.E.NULL.TRUNC should be the same field.
|
|
|
|
EQUATE D.E.UNIQUE TO 32 ;* SQL. 0=column may contain duplicate values. 1=column must contain unique values.
|
|
|
|
EQUATE D.E.LENGTH.LIMIT TO 33 ;* SQL. Length (in chars) of data. Needs to be
|
|
;* integrated with bonding.
|
|
|
|
EQUATE D.E.IN.TRUNC TO 39 ;* The first value in this field is either null, 0, or 1.
|
|
;* 0 or null means the default handling of input truncation:
|
|
;* if transferring a field into AREV would result in any loss of
|
|
;* information, an I/O error is returned. 1 allows the
|
|
;* the bond to truncate the data without returning an error.
|
|
;* In this case, either one or two values can follow the 1.
|
|
;* For character-based fields, a single value specifies what the
|
|
;* bond should read in when all information would be lost
|
|
;* (e.g., the field consisted of 3 field marks). For numeric-
|
|
;* based fields, the second value is the replacement for
|
|
;* numeric underflow and the third value is the replacement for
|
|
;* overflow.
|
|
|
|
EQUATE D.E.OUT.TRUNC TO 40 ;* Same as D.E.IN.TRUNC, except for output.
|
|
|
|
EQUATE D.E.USER1 TO 41 ;* This field is reserved for the application.
|
|
EQUATE D.E.USER2 TO 42 ;* ""
|
|
EQUATE D.E.USER3 TO 43 ;* ""
|
|
EQUATE D.E.USER4 TO 44 ;* ""
|
|
EQUATE D.E.USER5 TO 45 ;* ""
|
|
|
|
EQUATE D.E.OBJECT TO 51 ;* This field contains binary data; object code for the current field
|
|
|
|
*
|
|
* Equates that define the structure of the special record "%FIELDS%" found in each Arev Dictionary
|
|
* All of these fields are associated multivalued fields.
|
|
*
|
|
|
|

|
|
