我的程序如下：
3 Z7 L* k9 C7 B0 kbreed [dogs dog]
0 d7 R' v; B) L$ |+ `6 Cbreed [cats cat]1 M" R1 l: H8 Z0 o
breed [cows cow]

to setup

$ T, Z2 k: s2 N1 m set-default-shape dogs "dog"

这个是netlogo自带模型库里的模型中的程序，我新建文件再将其输入却提示错误：
( r& f M2 ^6 m. R# B, Gerror while observer running SET-DEFAULT-SHAPE in procedure SETUP& w. Q7 D2 F; \4 \% Y! ^! e

我用的版本是4.0.4 请大虾们指教下。thanks！ |
