What it does
CreateImageFromMemblock brings a Memblock object into being: it is how the rest of the program comes to have one. It takes imageID (an integer) and memID (an integer), and returns nothing. That is the first of 2 forms. imageID is the id you are giving an Image object: every later call names it by that number.

Form 1, you choose the id yourself
memblock = CreateMemblockFromFile("assets/data.dat")CreateImageFromMemblock(1, memblock)DO Sync()LOOPForm 2, the command hands back the id
imageFromMemblock = CreateImageFromMemblock(1)DO Sync()LOOPCreateMemblockFromFile is there to give the call something to act on; CreateImageFromMemblock is the line that matters. The DO … LOOP is not decoration: a classic BASIC program ends the moment it runs out of lines, and Sync() is what draws the frame.
