Get [#]fileNum, [recordNum|filePos], variable
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.
Sub ExampleRandomAccess
Dim iNumber As Integer
Dim sText As Variant REM 必須是變體型變數
Dim aFile As String
aFile = "c:\data.txt"
iNumber = Freefile
Open aFile For Random As #iNumber Len=32
Seek #iNumber,1 REM 指定開始位置
Put #iNumber,, "This is the first line of text" REM 用文字填入行
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
