... True, but the length of the indexer and the result (or assignment) will only work out to be the right length in some cases, by accident (for a scalar...
In the same vein I put a .Net based class to show how to create graphics on the APL Wiki. It uses the Mandelbrot Set as example. You can see the code at ...
Correct. On all counts. ... True, but the length of the indexer and the result (or assignment) will only work out to be the right length in some cases, by...
I always assumed working with simple data was quicker than nested. Below shows use of two operators: mf matches results from two functions; cf compares their...
Can anyone suggest a cheap and cheerful source for printing simple graph plots basically of the Y1, Y2, Y3.. versus time type, superimposed, on a single page....
Is there anyone out there with experience of integrating APL with "Web Sphere"? If so, I'd be interested to hear about the experience - please write to...
David, I may send you my plot functions based on aP207 emulator for Dyalog APL (there was an article in Vector about this). I am not sure on "cheerful", but...
... Right! Faster still. I thought inner product was always faster than running the reduction afterwards. I might just have to check out a few ∨.≠ and such...
I've got an application that figures out option prices on the fly, and its speed is ok for now, but if I want to trade different underlying markets I'll have...

Not sure this applies here but have you looked into mapped files? You could have a single shared 'variable' accessible by multiple tasks outside the ws. ......
well, if I used mapped files it wouldn't be in RAM but on disk, probably slower to take it off the disk than retrieve it from RAM ... From: Dan Baronet...
It used to be a common technique to use some of RAM for files. If that can be done then synchronizing the RAM file from a disk copy before real use should be...
As long as you have enough RAM there’s no difference between a memory mapped file and a variable in a WS. For any modern OS, memory is just a fast cache of...
Since version 12.0, Dyalog includes Causeway RainPro for free (as well as SharpPlot and NewLeaf), which is probably the best solution for your needs. ...

I have a client server application that uses a SQL database and ODBC. I need to capture the SQL statements that the client is sending to the server. Does...
Neeraj, You can enable tracing from the ODBC Data Source Administrator "Tracing" tab (Control Panel | Administrative Tools | Data Sources). That will log all ...
With the increasing number of Dyalog newbies, we have been asked to look into the possibility of producing some "APL Keyboards". So, we are considering having...
Morten: I have tried tracing. It shows the ODBC API calls such SQLAllocEnv, handles etc but no SQL statements. A colleague in the past used a program that gets...
Personally, I'm not interested. Rant follows... [0] Elsewhere there are reports that laptops are eating away at the desktop market - not sure how true this is....
I wonder if some kind soul will help me with a []NA problem. I am trying to use FileTimeToSystemTime that converts a standard file time (a FILETIME structure...
David, You might consider using the .NET interface capability. The .NET namespace System.IO has a FileInfo class that is fairly simple to use. It inherits from...
Ross, Thanks for that. However, it is not the standard time info for a file that I am trying to convert, but rather a FILETIME structure which could be...
That is not my experience... SQLPrepare is also an ODBC API call and the statement is one of the parameters. From a log created this morning: dyalog...
