# Instrución Line Input#

Reads a line from a sequential file into a variable.

### Sintaxe:

    Line Input #fileNum, variable

### Parámetros:

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

variable: The name of the variable that stores the result.

With the Line Input# statement, you can read strings from an open file into a variable. String variables are read line-by-line up to the first carriage return (Asc=13) or linefeed (Asc=10). Line end marks are not included in the resulting string.

### Exemplo:

      Sub ExampleWorkWithAFile
          Dim iNumber As Integer
          Dim sLine As String
          Dim aFile As String
          Dim sMsg As String
          aFile = "C:\Users\ThisUser\data.txt"
          iNumber = Freefile
          Open aFile For Output As #iNumber
          Print #iNumber, "Esta é unha liña de texto"
          Print #iNumber, "Esta é outra liña de texto"
          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

      Sub ExampleWorkWithAFile
          Dim iNumber As Integer
          Dim sLine As String
          Dim aFile As String
          Dim sMsg As String
          aFile = "~/data.txt"
          iNumber = Freefile
          Open aFile For Output As #iNumber
          Print #iNumber, "This is a line of text"
          Print #iNumber, "This is another line of text"
          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
