I suggest running this simple program to observe the instruction's behavior...
WHILE TRUE
STICK OUT SX,SY
?"SX:";SX:?"SY:";SY
GCIRCLE 200,120,50
GCIRCLE 200+SX*50,120-SY*50,5,#RED
WAIT 1
CLS:GCLS
WEND
Also, if you have a New 3DS or a Circle Pad Pro you can also use STICKEX in the exact same way to receive stick information from the C-Stick.
