Relative record part in EGL source format
You declare a record part of type relativeRecord in an EGL file, which is described in EGL source format.
An example of a relative record part is as follows:
Record myRelativeRecordPart type relativeRecord { fileName = myFile, keyItem = myKeyItem } 10 myKeyItem NUM(4); 10 myContent CHAR(76); endThe syntax diagram of a relative record part is as follows:
- Record recordPartName relativeRecord
- Identifies the part being of type relativeRecord and specifies the name. For the rules of naming, see Naming conventions.
- fileName = fileName
- The file name. For details on the meaning of your input, see Resource associations (overview). For rules, see Naming conventions.
- keyItem = keyItem
- The key item, which can be any of these areas of memory:
- A record item in the same record
- A record item in a record that is global to the program or is local to the function that accesses the record
- A data item that is global to the program or is local to the function that accesses the record
You must use an unqualified reference to name the key item. For example, use myItem rather than myRecord.myItem. (In a function, however, you can reference the key item as you would reference any item.) The key item must be unique in the local scope of the function that accesses the record or must be absent from local scope and unique in global scope.
The key item has these characteristics:
- Has a primitive type of NUM, BIN, DECIMAL, INT, or SMALLINT
- Contains no decimal place
- Allows for 9 digits at most
Only the get and add statements use the relative record key item, but the key item must be available to any function that uses the record for file access.
- structureItem
- A structure item, as described in Structure item in EGL source format.
