Determining If the End of a Text File Has Been Reached

Summary: When writing a macro that processes a text file, you may need to know when the end of the file has been reached. This is easy to do with the EOF function, described in this tip. (This tip works with Microsoft Word 97, Word 2000, Word 2002, Word 2003, and Word 2007.)

In other issues of WordTips you learn how to access text files from within a macro. Another command associated with sequential text files is the EOF function. If used on an open file, EOF returns a True or False condition, which indicates if the internal file pointer is located at the end of the file. This function is most often used when inputting information from a text file, as shown here:

Open "MyFile.Dat" for Input as #1
J = 0
While Not EOF(1)
    J = J + 1
    Line Input sMyString(J)
Wend

Tip #1397 applies to Microsoft Word versions: 97 | 2000 | 2002 | 2003 | 2007
