Problems with DOS SW44 Dictionary Creation

[Sandy Fleming]

Good morning, list!

I've just started typing in some BSL signs to my dictionary, but I'm having
some problems using SWDOS A4.

The main one is that when I enter my first sign in the BSL dictionary (I do
have the country and dictionary codes set to 044 and I can see that it is
using the BSL dictionary) it works fine, but then when I try to save
anything, it crashes with this error:

? Error: Protected file error in file SW044.DIN
  Error Code 1035, Status  0005
PC = 130E: 41A0; SS=2741, FP = 0004, SP = 4BE2

Am I supposed to unprotect the DIN file or is it protected for a reason? I
don't want to take too cavalier an approach to file protection because I
might end up with a corrupt dictionary with a lot of work in it that's
become completely inaccessible. So I thought I'd better ask first!

Thanks for any help anyone may be able to offer.
