Btrieve 5.10 command line parameters

[Harnek Singh]

Hi folks,

After a while away from Btrieve for DOS, I have to do some maintenance and
can't find my notes for it.

Anyone have the meanings and formats for the command line parameters for
btrieve for DOS single user ver 5.10 ?

I know stuff like /E to avoid extended memory, /T for transaction file but
that is about all I can remember !

Thanks and regards,
Harnek

These are the settings for the Btrieve.NLM. Obviously, not all will apply to
the EXE, but this gives you the general idea...
