The Open statement is part of the Microsoft Visual Basic for Applications (VBA)language. This command allows you to open a text data file for reading, modifying, or adding to the file.

The Open statement does not open the text data file in Word as a document. The file is open in VBA for manipulation by your VBA macro.

NOTE: The Open statement should not be used to open a program's own file types. For example, do not use this Open statement to access Word documents, a Microsoft Excel worksheet, or a Microsoft Access database. Doing so may cause file corruption and loss of file integrity.

This article assumes that you are familiar with the programming language that is being demonstrated and with the tools that are used to create and to debug procedures. Microsoft support engineers can help explain the functionality of a particular procedure, but they will not modify these examples to provide added functionality or construct procedures to meet your specific requirements. The correct syntax for the Open statement is as follows:
   Open pathname For mode [access] [lock] As [#]filenumber [Len=reclength]				
The Open statement syntax has the following parts.

Part            Description---------------------------pathname        Required. String expression that specifies a file name may                include directory or folder, and drive.    mode        Required. Keyword specifying the file mode: Append, Binary,                Input, Output, or Random. If unspecified, the file is                opened for Random access.  access        Optional. Keyword specifying the operations permitted on                the open file: Read, Write, or Read Write.    lock        Optional. Keyword specifying the operations permitted on                the open file by other processes: Shared, Lock Read, Lock                Write, and Lock Read Write.filenumber      Required. A valid file number in the range 1 to 511,                inclusive. Use the FreeFile function to obtain the next                available file number.reclength       Optional. Number less than or equal to 32,767 (bytes). For                files opened for random access, this value is the record                length. For sequential files, this value is the number of                characters buffered.				

Statement Example

Sub OpenExample()   Dim sFirst, sLast, sAddress, sCity, sState, sZip As String   ' CREATE DATA FILE   ' Open file for input.   Open "Datafile.txt" For Output As #1   ' Write data to file.   Write #1, "John", "Doe", "An Address", "A City", "A State", "A Zip"   ' Close File.   Close #1   ' RETRIEVE DATA FROM FILE   ' Open file for input.   Open "Datafile.txt" For Input As #1   ' Loop until the end of file is reached.   Do While Not EOF(1)      ' Read data into variables.      Input #1, sFirst,sLast,sAddress,sCity,sState,sZip      ' Print data to Debug window.      Debug.Print sFirst,sLast,sAddress,sCity,sState,sZip   Loop   ' Close file.   Close #1End Sub				

This macro creates or opens a file called Datafile.txt and puts the commaand quotation mark delimited data into the file. The data can then later beretrieved using the Input # statement.
