Syntax:

Put Statement diagram


Put [#]fileNum, [recordNum|filePos], variable

Parametrar:

fileNum: Any integer expression that defines the file that you want to write to.

recordNum, filePos: For relative files (random access files), the number of the record that you want to write.

För binära filer (Binary-åtkomst): positionen hos den byte i filen där du vill börja skriva.

variable: Name of the variable that you want to write to the file.

Observera för relativa filer: Om innehållet i den här variabeln inte motsvarar längden på den post som anges i bisatsen Len i Open-satsen, så fylls utrymmet mellan den nyss skrivna posten och nästa post ut med befintliga data från den fil du skriver till.

Observera för binära filer: Innehåller i variablerna skrivs till den angivna positionen, och filpekaren infogas direkt efter den sista byten. Inget utrymme lämnas mellan posterna.

Exempel:


  Sub ExampleRandomAccess
      Dim iNumber As Integer
      Dim sText As Variant ' Måste vara av typen variant
      Dim aFile As String
      aFile = "C:\Users\ThisUser\data.txt"
      iNumber = Freefile
      Open aFile For Random As #iNumber Len=32
      Seek #iNumber,1 ' Placera i början
      Put #iNumber, , "This is the first line of text" ' Fill line with text
      Put #iNumber, , "This is the second line of text"
      Put #iNumber, , "This is the third line of text"
      Seek #iNumber,2
      Get #iNumber, , sText
      Print sText
      Close #iNumber
      iNumber = Freefile
      Open aFile For Random As #iNumber Len=32
      Get #iNumber, 2, sText
      Put #iNumber, , "This is a new text"
      Get #iNumber, 1, sText
      Get #iNumber, 2, sText
      Put #iNumber, 20, "This is the text in record 20"
      Print Lof(#iNumber)
      Close #iNumber
  End Sub


  Sub ExampleRandomAccess
      Dim iNumber As Integer
      Dim sText As Variant ' Must be a variant
      Dim aFile As String
      aFile = "~/data.txt"
      iNumber = Freefile
      Open aFile For Random As #iNumber Len=32
      Seek #iNumber,1 ' Position at beginning
      Put #iNumber, , "This is the first line of text" ' Fill line with text
      Put #iNumber, , "This is the second line of text"
      Put #iNumber, , "This is the third line of text"
      Seek #iNumber,2
      Get #iNumber, , sText
      Print sText
      Close #iNumber
      iNumber = Freefile
      Open aFile For Random As #iNumber Len=32
      Get #iNumber, 2, sText
      Put #iNumber, , "This is a new text"
      Get #iNumber, 1, sText
      Get #iNumber, 2, sText
      Put #iNumber, 20, "This is the text in record 20"
