Hi Alexey,

Relative to what? If the crosshair, in pc-rnd this works:

Cursor(pan, X, Y, mm)
PasteBuffer(ToLayout, Crosshair)

it's a cheat: it really moves the crosshair and then places the buffer at 
the new location. 

Please note that Cursor() is a rather old action and has calling 
conventions that are not in line with the conventions of modern actions. 
For example Y is flipped, positive goes up, not down (when looked from the 
top), and the unit needs to be specified in a separate arg.

We do have provisions in the code for relative placement in PasteBuffer(), 
but I couldn't decide what it should be relative to, so it's relative to 
0;0 -- which means absolute. We can easily change that if we figure what 
exactly it should do and why.


HTH,

Igor2
