[Gambas-user] fastest way to "zero-out" a huge binary file

[kevinfishburne]

I need to create an 8 gigabyte binary file with zero values throughout it. Is
there a faster way to do this than to create a big string of zeros and write
it to the file multiple times? What I'm doing right now works but seems like
a really ugly method:

' Zero-out the file.
Zero = Chr$(0) & Chr$(0) & Chr$(0) & Chr$(0) & Chr$(0) & Chr$(0) & Chr$(0) &
Chr$(0) & Chr$(0) & Chr$(0) & Chr$(0) & Chr$(0) & Chr$(0) & Chr$(0) &
Chr$(0) & Chr$(0) & Chr$(0) & Chr$(0) & Chr$(0) & Chr$(0) & Chr$(0) &
Chr$(0) & Chr$(0) & Chr$(0) & Chr$(0) & Chr$(0) & Chr$(0) & Chr$(0) &
Chr$(0) & Chr$(0) & Chr$(0) & Chr$(0)
FOR counter = 1 TO 65536
  Zeros = Zeros & Zero
NEXT
FOR counter = 1 TO 4096
  WRITE #Elevation, Zeros
NEXT
