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:
The Open statement syntax has the following parts.
Open pathname For mode [access] [lock] As [#]filenumber [Len=reclength]
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.
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.
