Owning Palette: Datalog Functions
Requires: Base Development System
Opens an existing datalog file, creates a new datalog file, or replaces an existing datalog file, programmatically or interactively using a file dialog box. This function does not work for files inside an LLB.
You can optionally specify a dialog prompt or default filename. Use this function with the intermediate Write Datalog or Read Datalog functions. Use the Close File function to close the reference to the file.
|record type can be any data type. Wire a cluster matching the record data type and cluster order to this input when creating datalog files.|
|prompt is the message that appears above the list of files and directories or folder in the file dialog box.|
|datalog path is the absolute path to the file. If you do not wire datalog path, the function displays a dialog box from which you can select a file. If you specify an empty or relative path, this function returns an error.|
|operation is the operation to perform. Error 43 occurs if you cancel the dialog box.
|access specifies how you plan to access the file.
|error in describes error conditions that occur before this node runs. This input provides standard error in functionality.|
|refnum out is the reference number of the open file. The value is Not A Refnum if the file cannot be opened.|
|cancelled is TRUE if you cancel the file dialog box or if you do not select the replacement in an advisory dialog box.|
|error out contains error information. This output provides standard error out functionality.|
