Document management, Direct access functionality


Opens a file in direct access mode. This allows large files to be processed. The file will not be accessible by other processes until the file is closed using the one of the following functions: DACloseFile, DAAppendFile or DASaveAsFile. Read only files can be opened and all other direct access functions will work but DAAppendFile will not work as the file cannot be written.
