Thanks, Paul. Wasn't sure if Bill Bardsley was still there, but will do!

It's the x,y, arrays, dimension n, in simdem53. There seems to be a hardcoded limit of 2000 to those arrays. Apart from the ...

I sm working on image enhancement coding, and want to use SIMDEM to do some simple scatter plots showing colour profiles of images.

Problem is that working with images that are typically thousands ...

Many thanks, Paul. Yes, something stirs in my memory. I did this once before. This is the problem when coding only intermittently over a period of many years! I shall give that a try.

I have a simple program that reads and displays an image file using DISPLAY_DIB_BLOCK@. It works just fine.

I now want to use the mouse to get a few pixel positions in the image, but seem to be ca ...

Hi Eddie-

Wow! You've been puzzling over this for 8 years? I guess I'm duty-bound to try it out, if I can find the place in my coding that needed it. I'm not even working on the same project any mo ...

Many thanks, John - Indeed that is an option, not to use an external simulation package but simply to code the entire simulation in FTN95 and present the animation using Clearwin+ graphics. Integratio ...

For a new EU research project, I need to find suitable simulation software to model a robotic 'ecosystem' producing minerals from an underground mine. I already have the software to model the 3D geolo ...

Hi John -
We are finding that by far the slowest part of our processing is the data acquisition - transfer from the robot or from a central server. We are now using USB3.1 and a 2-terabyte SSD which ...

hi mecej - my timestamps are Unix plus. For some reason our robot engineers decided they needed nanosecond precision, so we have horrendous 19-digit timestamps. I have reduced these by extracting micr ...

Many thanks for all this, John! In the past I haven't paid much attention to sorting, just used shell sort for smaller data sets, and merge sort for larger. Avoided bubble sort like the plague. And ot ...

Many thanks for taking the time to test this, John. I never got the 85 million sorted within FTN95 because of the array allocation problem. The workaround was to export the file to an SQLite database ...

Indeed so - before sorting. That is the reason the sort is necessary. And yes indeed, one option is to divert the out-of-order timestamps into a separate file, then sort that and merge it back. That's ...

Thanks John - I think you're right, and the problem had nothing to do with the allocatable arrays. I found a workaround for that one and will come back to it later.

I now have another problem. All ...
