Returns a Long specifying the current read/write position within an open file.
The required filenumber argument is any valid Integer file number.
The following describes the return value for each file access mode:
|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.|
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.
