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

Parameters:

fileNum: Any integer expression that determines the file number.

recordNum: For files opened in Random mode, recordNum is the number of the record that you want to read.

For files opened in Binary mode, filePos is the byte position in the file where the reading starts.

If recordNum and filePos are omitted, the current position or the current data record of the file is used.

variable: Name of the variable to be read. With the exception of object variables, you can use any variable type.

Example:


  Sub ExampleRandomAccess
      Dim iNumber As Integer
      Dim sText As Variant ' Musí byť variant
      Dim aFile As String
      aFile = "C:\Users\ThisUser\data.txt"
      iNumber = Freefile
      Open aFile For Random As #iNumber Len=32
      Seek #iNumber,1 ' Presun na začiatok
      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

      Get #iNumber, , sText
      Print sText
      Close #iNumber
      iNumber = Freefile
      Open aFile For Random As #iNumber Len=32
      Get #iNumber, 2, sText
