Syntax:

Input Statement diagram


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.

Podaci i podatkovni tipovi u otvorenoj datoteci moraju biti u istom poretku kao i varijable koje su proslijeđene u "var" parametru. Ako dodijelite ne-brojčanu vrijednost brojčanoj varijabli, vrijednost "0" će biti dodijeljena u "var".

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.

Ako se pri čitanju podatkovnog elementa došlo do kraja datoteke, dolazi do greške i proces se prekida.

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
