True to its BASIC roots, VBA allows you to do file input on sequential files. This means you can open and read a sequential text file, loading the information from the file into string variables. The steps are simple. You only have to open the file, get the input, and then close the file. The following code is a common example of reading from a sequential file:
Dim Raw As String Dim NumValues As Integer, J As Integer Dim UserVals() As String Open "MyFile.Dat" For Input As #1 Line Input #1, Raw NumValues = Val(Raw) ReDim UserVals(NumValues) For J = 1 to NumValues Line Input #1, UserVals(J) Next J Close #1
In this example you should note that the first line read from the text file (MyFile.Dat) is assumed to contain a value that indicates how many items are to be read in from the file.
