Returns a Long specifying the current read/write position within an open file.
Syntax
Loc(filenumber)
The required filenumber argument is any valid Integer file number.
Remarks
The following describes the return value for each file access mode:
| Mode | Return value |
|---|---|
| Random | Number of the last record read from or written to the file. |
| Sequential | Current byte position in the file divided by 128. However, information returned by Loc for sequential files is neither used nor required. |
| Binary | Position of the last byte read or written. |
Example
This example uses the Loc function to return the current read/write position within an open file. This example assumes that TESTFILE is a text file with a few lines of sample data.
Dim MyLocation, MyLine
Open "TESTFILE" For Binary As #1 ' Open file just created.
Do While MyLocation < LOF(1) ' Loop until end of file.
MyLine = MyLine & Input(1, #1) ' Read character into variable.
MyLocation = Loc(1) ' Get current position within file.
' Print to the Immediate window.
Debug.Print MyLine; Tab; MyLocation
Loop
Close #1 ' Close file.
