Length of source : 314 bytes
Length of executable : 38 bytes
Execution : To execute, drag and drop "ASM3Tree.prg" into a started up C64 VICE Emulator V3.5.
How it works : A loop reads in run lengths for the number of "*" to print on each row and also determines the start position based upon this length. It also uses a Kernal scroll screen routine to move the entire screen up a row to make space for the new row of the Christmas tree.
