) AS USUAL

Parameters

oFSSource
Type: Usual
The source file is opened in shared, read-only mode, and can be open elsewhere in this or some other application. This function attempts to open <oDBFSource> | <oFSSource> | <cSource> in shared mode.  If the file does not exist, a runtime error is raised.  If the file is successfully opened, the operation proceeds.  Refer to the 'Concurrency Control' chapter in the Programmer's Guide for more information on resolving concurrency conflicts.
aFieldList
Type: Usual
An array of the fields from the source file that are to be included.  The default is all fields.
cbForBlock
Type: Usual
The condition evaluated for each record in the scope; if TRUE, the record is included in the processing.  It provides the same functionality as the FOR clause of record processing commands.
cbWhileBlock
Type: Usual
The condition evaluated for each record from the first record until the condition returns FALSE.  It provides the same functionality as the WHILE clause of record processing commands.
uScope
Type: Usual
The range of records to process, providing the same functionality as the ALL, REST and NEXT clauses of record processing commands. Value Description DBSCOPEALL The scope is all the records in the table.  This is the default, although if a WHILE condition is specified, the scope becomes DBSCOPEREST. DBSCOPEREST The scope is the remaining records in the table from the current position. <nRecords> The scope is the next <nRecords> records.
cDriver
Type: Usual
The name of the RDD that will service the data server.  If not specified, the default RDD as determined by RDDSetDefault() is used.
aRdd
Type: Usual
A one-dimensional array with the names of RDDs from which the main RDD inherits special functionality.  This allows you to use RDDs with special capabilities, like encryption or decryption, for different data servers with different database drivers.  These RDDs overlay special functions of the main RDD (specified with the <cDriver> argument).  If multiple RDDs (specified with this argument) implement the same function, the function associated with the last RDD in the list takes precedence.  If <aRDDs> is omitted, no additional RDDs are assumed.

Return Value

Type: Usual
TRUE if successful; otherwise, FALSE (although records still might have been appended).
Remarks
Sends a NotifyIntentToMove message before the operation.  Sends a NotifyFileChange message, if any record was appended.
