Strange error messages
I've been getting some strange-looking error messages from V3.12. E.g. (in DBrowser): (2+1)) ERROR: Encountered " ")" ") "" at line 1, column 6. In general, the word "Encountered" seems to followed by a repetition of the rogue token. Here's another example: tu...

How about a LENGTH operator?
I found the package of FOREIGN string operators not only very useful but also informative--even though I don't know Java I might just be able to learn enough from them to write a simple FOREIGN operator myself! I was surprised not to find OPERATOR LENGTH ( C CHAR ) RETURNS INTEGER in that package, b...

Display of character stirng results
This is just an idle observation and should not be treated with any degree of urgency at all. If there's a prioritised list of planned enhancements, please put it at the bottom if you plan to accept it at all. There's a curious difference in treatment of tuple{x 'abc'} and just 'abc'. The result dis...

-f option doesn't work with paths including blanks
In version 0.3.8 I had been using the following Windows commands to invoke Dbrowser: s: cd \Rel\V3.8 java -jar DBrowser.jar -f"d:\Rel version 3\BirdTrack.0.3.8" However, when I installed version 0.3.9 in s:\Rel\V3.9 and set up a new directory, d:\Rel version 3\BirdTrack.0.3.9, for my datab...

Backup in 0.3.9 on Windows Vista uses invalid filename
With the location box showing local:d:\Rel-version-3\BirdTrack.0.3.9, I clicked on Backup. Backup invited me to save the backup using the following filename: relbackup_d:_Rel-version-3_BirdTrack_0_3_9_2008_July_29_01_44_PM.d I decided to take that and I eventually got the message saying the backup h...

Re: V2 features apparently no longer supported
The return of FOR (the <iterate statement>) and ORDER is imminent, possibly as soon as version 0.3.10. Along with these, I'm inclined to provide a command-line switch to optionally disable such extensions, for use in pedagogical (or other) contexts where strict adherence to Tutorial D is desirable....

V2 features apparently no longer supported
I'm not sure you would regard this as a bug, but I couldn't find a more appropriate section to raise this issue in. Two V2 features I was using seem to be no longer available. The first is <iterate statement>, though the use I was putting this to is now subsumed by the new "enhanced" featu...

Thank you, Dave. I was expecting a reply of this sort. The problem doesn't bother me greatly and I can live with it.

Re: Changing the default database in Rel and DBrowser
Thank you, Dave. This will be very useful to me, now that I know about it!
I made a lot of trouble for myself by having spaces in my directory name. I eventually remembered to use double quotes around the entire path. You might want to mention that requirement when you document this feature.

switch back to enhanced causes exception
Sorry about this--it appears to be an "out of memory" exception, perhaps caused by an unreasonably large query result. I'm sure I can live with "no action", if necessary, but I'd like to know your position and policy regarding such problems. With "Enhanced" turned on, I...

phoney deadlocks after restore from backup
Using Rel Version 0.3.8, I successfully (?) restored my database from the backup taken using Rel Version 0.3.5 Alpha, using the supplied script, DatabaseToScript.d. However, when I subsequently tried the simplest possible query against one of my relvars, I got a deadlock exception (see below). The p...

Re: Installed JDK 6 but OperatorsChar.d doesn't work
Yes, I found I had several copies of Java on my computer. In fact, in c:\Program files\Java I found 7 or 8 directories for various different versions of JRE and JDK. It seems, then, that every time I've accepted the invitation to upgrade Java the previous version has been left intact. Also, my insta...

Re: Installed JDK 6 but OperatorsChar.d doesn't work
Okay, now OperatorsChar.d works, but invocation of the defined operators doesn't. They all give the same exception, "String index out of range: 1." Here's an example: EQUALS_IGNORE_CASE('Darwen','DARWEN') ERROR: java.lang.StringIndexOutOfBoundsException: String index out of range: 1 java.l...

Re: Installed JDK 6 but OperatorsChar.d doesn't work
Yes, my system path had some nonexistent directories in it. I fixed that and now javac -version works. But now other things have gone wrong, so I'll get back to you when I've investigated further.
