D3 OSFI Explored

Access to the OS file system from D3 is possible through the OSFI – the Open System File Interface. Over time I’ve noticed some confusion in how our colleagues use and under-use this feature, so I thought I’d clarify a couple points here.

D3 Windows or Linux?

I saw another question today about whether a VAR should recommend D3 Windows or D3 Linux. Knowing many sites that have moved from Windows to Linux, and those that have not, I thought I’d post my thoughts on it here for a more general audience.

Dirt-simple D3 activation – and Web Services

I don’t know how many people know this but activating D3NT is a real breeze in v7.5.x because activations are provided transparently over the internet. Hmmm, this seems to dove-tail with the Web Services blogs.

Lonely Shell Variables – Part 2

Back in March 2008 I wrote a blog here called Lonely Shell Variables. Today I was fiddling with shell variables in D3 (also called Environment variables) and once again I marvelled at the power and flexibility – but I’d bet the number of people who really use this functionality can be counted on a single [...]

To free, or not to free? That is the question.

I needed to get information out of D3 and there is no standard function to get it. After a couple emails with TigerLogic support, I was able to write two lines of code to get what I needed. Wow, that’s cool. Now should I be a good community citizen and give it away? Should I [...]

What is a “large” select list?

A question came up in CDP about what a “large” dynamic array is, when used as a select list, and when lists should be processed as dimensioned arrays versus dynamic arrays. The answer can be more complex than one might think.

D3 FlashBASIC Part 2

A while back I wrote a blog entry on how D3 FlashBASIC works. That blog/article was recently re-published in International Spectrum magazine. Yay! In the QM forum a question came up as to how D3 caches BASIC object code. I thought the little I knew about the topic would serve as a supplemental update to that [...]

D3 Precision – Who says MV doesn’t have data types?

I got an email about an issue with high-precision data passed to NebulaXLite. That started several exchanges with Tiger Logic Technical Support, and I’m summarizing what I’ve learned here.

D3 FlashBASIC History and Usage

Questions frequently arise in forums about how FlashBASIC works. So I thought I’d summarize it here. First, a primer on compilation and object code in general

Lonely D3 Shell Variables

A question came up in comp.databases.pick that asked how we could use a pre-defined set of values in a D3 query. For example: SORT CUSTOMERS WITH STATE "AZ" "CA" "NM" "OR" … but getting the state codes dynamically. Sure, we can do that, using shell variables.
