I'm trying to use a block file as virtual memory and ran into a problem.

Using this code
===
  \ Use (or create) a block file
      s" mem.fb" use

      1 block drop

      1024 constant bytes/block
===

When invoked like this
   gforth fitz.fs

I get the following error:
===
in file included from *OS command line*:-1
fitz.fs:4: File I/O exception
1 >>>block<<< drop
Backtrace:
$7CEC4522BD40 throw
$6118C2B8D948
===

What am I missing?

TIA,
Fitz
