- Surfer always sets the blanking flag to 1 when digitizing.  Open the BLN file in the worksheet, set the blanking flag value of cell B1 to 0, and save the changes.

- Another method is to use a script BlankOutside.bas to read the file and write out the first line with the blanking flag set to 0.

Run the Surfer Scripter with the Windows Start | Programs | Golden Software Surfer 8 | Scripter menu command, open the file with the File | Open command, and run the script with the Script | Run command.

Sub Main
    file1 = GetFilePath(,"bln","c:\incoming\","Enter BLN File Name")
    Debug.Print file1
    If file1 = "" Then End
    file2 = Left(file1,Len(file1)-4)+"BlankOutside.bln"
    Open file1 For Input As #1
    Open file2 For Output As #2
    Line Input #1,a
    a = Left(a,Len(a)-1) + "0"
    Print #2,a
    While Not EOF(1)
        Line Input #1, a
        Print #2,a
    Wend
    MsgBox(file2+" has been created")

End Sub

    An easy way to remember this is 1=blank Inside, and 0=blank outside so 1=I and 0=O
