我的程序如下：( M4 V _. m: o' z
breed [dogs dog]5 p7 X$ x; r- c8 h3 x: Y
breed [cats cat]& Y8 r! t1 {6 d
breed [cows cow]
! A* ~& Q0 b1 I. z

set-default-shape dogs "dog"0 y6 d( N9 G$ o! n L6 Q' c, Y
set-default-shape cats "cat"' l# v5 e/ o7 Z
set-default-shape cows "cow"; Y* J6 B6 x I4 o1 ~. c& ?: m

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：; ~: w- l' }0 u4 t
