我的程序如下：
4 P( F5 f$ g% X9 }breed [dogs dog]
! L8 @1 o9 A/ g* R" M* abreed [cats cat] A2 A, D8 }) X8 Z1 q
breed [cows cow]1 E; r9 m/ T& ^) [' p
7 t2 z* T ], A" U4 M2 p& y
to setup6 q1 P( d. A* z8 D" m# }3 o) M
clear-all$ P# }0 M' G; l1 F
set-default-shape dogs "dog" Z6 D7 p$ T$ E& w
set-default-shape cats "cat"+ V% f7 k5 X+ @( g5 {
set-default-shape cows "cow"+ s. }$ d" ~: l" \+ X& q/ h
ask patch 0 1 [ sprout-dogs 1 ]2 P& m' z- m5 e/ g( G

ask patch 0 -1 [ sprout-cows 1 ]
. V) }# G/ L1 D: S& e/ J2 k u8 send
; c" K! r. f/ X
% P. h- A; @ D* z0 l
5 K2 @6 b! J2 x L6 m5 ~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：4 a9 {/ W3 ^( z* s1 A% Y
error while observer running SET-DEFAULT-SHAPE in procedure SETUP
9 U' c9 f" v: ?"dog" is not a currently defined turtle shape
/ ~3 h0 h; Q; G* {$ U: _' X& {/ g(halted running of setup)
4 I& h; t( X A, H- P; k5 ]. c; j: b. C0 C2 o9 e( ~" l
# y, D- g. ^2 ~
