If I might weight in a little here. Building on what Thomas just stated, I was initially reluctant to move away from 5.x in a large project I had that was independently certified for safety use. I tried 'migrating' from 5.x to 6 when the change came about. It was a nightmare, all kinds of errors, so...

Harrison,
Great job. I've been wanting to do more work in GDIPlus inside of VIP since I presented my paper at the VIP ALC back in 2006. I've done some minor tinkering but too many issues/demands in my day job to devote much time to it unfortunately. Glad to see this.

Years ago, back in the PDC 3.x days I remember doing a comparison between SWI and PDC Prolog (as it was called then). PDC was noticeably faster in all my tests, event when used as the PIE. I can't vouch for the current versions of VIP v. SWI because I don't use SWI at all. (I am a little biased towa...

Like Thomas, not in my area of expertise, BUT I believe if they are connected to the internet (or corporate network), time can be pulled form a Corporate Server or from an internet 'clock' (there are a few of these). https://time.is/about www.time.gov tf.nist.gov/tf-cgi/servers.cgi do a google searc...

Harrison,
A 'dumb' suggestion.

Have you tried breaking up the file being imported to see if you can do multiple successive file reads?

I had a situation years ago where I could not import the entire single file but if I broke into two, I could import everything using two reads.

Thanks, I will download and check it out. (i'm still using 7.4 CE for my own use, wasn't sure about PIE in PE)

PIE

Thomas,
Is the PIE still available for use in VIP, more specifically, in the PE version?

I am getting ready to teach an AI class and would like to use the PIE as an intro to Prolog (will also help introduce the VIP environment to some who have never seen it before :wink: ).

Welcome back.

See: http://wiki.visual-prolog.com/index.php ... ence/Facts

:= is the assignment operator (for facts)
= is equality test if both are bound variables or assignment if one is free.

While I don't have a solution I can offer a suggestion that might help some. I've played this 'game' before and I find it challenging (but fun!). It is similar to Sudoku (each number can only be used once in a column or row) but with the added twist of summing the numbers. I suggest looking at the S...

Harrison, I would first verify that M8 tested it in 'user' mode and not Administrator mode. Win 10 has a lot more restrictions in that regard (as did Win7 compared to XP). I had a bunch of programs that worked perfectly in XP but would only run in Win7 (and above) in Admin mode (the application elev...

don't know for sure but it looks like it will just pull what ever is currently store in the memory location for the variable.

Sort of surprised though that you are not getting an 'unbound variable' error at compile time.

my half cent perspective: I never use the logical operators AND, OR within a clause to execute two different actions/results as they can be really problematic when trouble shooting. I always use extra clauses. (call it a personal preference :-) ) in the case of a(...) OR b(...) I would use what Thom...
