So let's just say I have a redbook file called something.rb, and I go to
decode it with the dcredbook_vg decoder (this happens with all the
dcredbook decoders)....

dcredbook -v 1 -d ./dcredbook.log 'VG|something.vgf' < something.rb

or even:

dcredbook -v 1 -d ./dcredbook.log 'VG|%P-YYYYMMDD_HHNN.vgf' < something.rb

It fails with this error:

[30318] 130306/0127[GEMPLT -1]  NMBRER - Mailbox read.
[30318] 130306/0127[GEMPLT -8]  NDVICE - Device not set.
[30318] 130306/0127[GG -7]  No map drawn.

However if I just did this:

dcredbook -v 1 -d ./dcredbook.log 'VG' < something.rb

It decodes just fine into a file called vgf.vgf

Anytime I put anything into the file name area, it fails, but if it's
empty, it works just fine. I'm thinking this might be a bug, as other
programs such as GPMAP have no issues with the DEVICE parameter, including
when I put a file name in it. In fact, I have no issues with gempak other
than this issue.
