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

NOTE: The Open statement does not open the file into the workspace, it merely opens the file for manipulation by your macro.

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

The correct syntax for the Open statement is: 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 #1

End Sub This macro creates or opens a file called Datafile.txt and puts the comma and quotation mark delimited data into the file. The data can then later be retrieved using the Input # Statement.
