Line Input# -lauseella luetaan merkkijonoja avoimesta tiedostosta muuttujaan. Merkkijonomuuttujat luetaan rivi kerrallaan ensimmäiseen telanpalautukseen (CR, Asc=13) tai rivin siirtoon (LF, Asc=10). Rivin lopetusmerkit eivät tule merkkijonoon.

Example:


Sub ExampleWorkWithAFile
Dim iNumber As Integer
Dim sLine As String
Dim aFile As String
Dim sMsg As String
    aFile = "c:\data.txt"
    iNumber = Freefile
    Open aFile For Output As #iNumber
    Print #iNumber, "Tämä on tekstirivi."
    Print #iNumber, "Tässä on toinen rivi tekstiä"
    Close #iNumber
    iNumber = Freefile
    Open aFile For Input As iNumber
    While Not eof(iNumber)
        Line Input #iNumber, sLine
        If sLine <>"" Then
            sMsg = sMsg & sLine & chr(13)
        End If
    Wend
    Close #iNumber
    MsgBox sMsg
End Sub
