# Input# Statement

Reads data from an open sequential file.

### Syntax:

    Input #fileNum {,|;} var1 [, var2 [, ...]]

### Parameters:

fileNum: Number of the file that contains the data that you want to read. The file must be opened with the Open statement using the key word INPUT.

var: A numeric or string variable that you assign the values read from the opened file to.

The Input# statement reads numeric values or strings from an open file and assigns the data to one or more variables. A numeric variable is read up to the first carriage return (Asc=13), line feed (Asc=10), space, or comma. String variables are read to up to the first carriage return (Asc=13), line feed (Asc=10), or comma.

Data and data types in the opened file must appear in the same order as the variables that are passed in the "var" parameter. If you assign non-numeric values to a numeric variable, "var" is assigned a value of "0".

Records that are separated by commas cannot be assigned to a string variable. Quotation marks (") in the file are disregarded as well. If you want to read these characters from the file, use the Line Input# statement to read pure text files (files containing only printable characters) line by line.

If the end of the file is reached while reading a data element, an error occurs and the process is aborted.

### Example:

    Sub ExampleWorkWithAFile
        Dim iCount As Integer, sFileName As String
        Dim sName As String, sValue As Integer
        sFileName = "C:\Users\ThisUser\data.txt"
        iCount = Freefile
        ' Write data ( which we will read later with Input ) to file
        Open sFileName For Output As iCount
        sName = "Hamburg" : sValue = 200
        Write #iCount, sName, sValue
        sName = "New York" : sValue = 300
        Write #iCount; sName, sValue
        sName = "Miami" : sValue = 459
        Write #iCount, sName, sValue
        Close #iCount
        ' Read data file using Input
        iCount = Freefile
        Open sFileName For Input As iCount
        Input #iCount, sName, sValue
        MsgBox sName & " " & sValue
        Input #iCount; sName, sValue
        MsgBox sName & " " & sValue
        Input #iCount, sName, sValue
        MsgBox sName & " " & sValue
        Close #iCount
    End Sub
