Parameters

cTargetFile (Optional)

Type: Usual
The name of the target database file to write the totaled records, including an optional drive, directory, and extension. See SetDefault() and SetPath() for file searching and creation rules.
The default extension for database files is determined by the RDD .
If cTargetFile does not exist, it is created.
If it exists, this function attempts to open the file in exclusive mode and, if successful, the file is overwritten without warning or error.
If access is denied because, for example, another process is using the file, NetErr() is set to TRUE.

cbKey (Optional)

Type: Usual
A key expression specified as a code block.

acFields (Optional)

Type: Usual
The fields to be totaled specified as an array of strings.

cbForCondition (Optional)

Type: Usual
A code block that defines a condition that each record within the scope must meet in order to be processed.

cbWhileCondition (Optional)

Type: Usual
A code block that defines another condition that each record must meet in order to be processed. As soon as a record is encountered that causes the condition to fail, the operation terminates.
If no scope is specified, cbWhileCondition changes the default scope to lRest.
You define the scope using one of these three, mutually exclusive arguments.
The default is all records.

nNext (Optional)

Type: Usual
The number of records to process, starting at nRecord. Specify 0 to ignore this argument.

nRecord (Optional)

Type: Usual
A single record number to process. Specify 0 to ignore this argument.

lRest (Optional)

Type: Usual
TRUE processes only records from nStart to the end of the file. FALSE processes all records.

lNoOpt (Optional)

Type: Usual
Disable (Rushmore) optimizations (not supported yet).
