Soo Far i use the Karel to initiate a config var like in the manual, but I didin't find how to push it on a XYZWPR var.
I think i will be in obligation to translate into a position data type to use it.
VAR
config_var1, config_var2: CONFIG
pos_var: POSITION
seam_path: PATH
i: INTEGER
BEGIN
config_var1 = pos_var.config_data
config_var1 = config_var2
config_var1.cfg_turn_no1 = 0
IF pos_var.config_data.cfg_flip THEN...
FOR i = 1 TO PATH_LEN(seam_path) DO
seam_path[i].node_pos.config_data = config_var1
ENDFOR
In hope it will help you.
