Robert Campbell asked me to forward this message to the BlackBox mailing
list for him:

-------------------------------
If I type the address "http://a.tile.openstreetmap.org/17/64377/40836.png"
into a web browser I get to see a 256 * 256 pixel bitmap (which happens to
be a map of my house which I added myself this Christmas, but that is all
irrelevant).

How would I write a BlackBox program to fetch this tile, and either turn it
into an internal BlackBox bitmap, or save it directly as a .png file.

I do use the FreeImage subsystem, so can handle bitmaps and .png files
within BlackBox, but I have no idea how to start on the internet stuff.

Maybe the answer is in the Comm SubSystem, which I have used (a long time
ago) to communicate PC to PC over ethernet and over the USB?

Regards

Robert
