Get Statement diagram

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

Parámetros:

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.

variábel: Nome da variábel que desexa ler. Use calquera tipo de variábeis excepto as de obxectos.

Exemplo:

Sub ExampleRandomAccess
    Dim iNumber As Integer
    Dim sTexto As Variant REM Debe ser unha variante
    Dim aFile As String
    aFile = "C:\Users\ThisUser\data.txt"
    iNumber = Freefile
    Open aFile For Random As #iNumber Len=32
    Seek #iNumero,1 REM 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"
    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"
    Print Lof(#iNumber)
    Close #iNumber
