Length = Lof ( Stream AS Stream ) AS Long

Returns the length of the opened stream Stream.

OPEN sFileName FOR READ AS #hFile

PRINT "File length is "; Lof(hFile)

If the stream is not a file, i.e. a Process or a Socket, then it returns the number of bytes that can be read at once.

PUBLIC SUB Process_Read()

  DIM sBuffer AS String

  PRINT "I can read "; Lof(hLAST)
  ' Read them
  READ #hLAST, sBuffer, Lof(hLAST)
