语法看不懂，能帮忙解释一下吗？
下面的语句中ask patch和create-initial-turtles 后面接的[ ]中的语句是什么含义，其中非原语的都是定义的全局或者外部变量。语法有点奇怪，谁能帮我解释一下吗？多谢:)to make-turtles
ask patch 0 0 [
create-initial-turtles num-random-min "random-min" violet
create-initial-turtles num-random "random" brown
create-initial-turtles num-random-away"random-away"pink
create-initial-turtles num-open-min "open-min" blue
create-initial-turtles num-open-min-max "open-min-max" orange ]
set-common-variables
end
to create-initial-turtles
ask n-of n (patches in-radius initial-radius with )
[ sprout 1
[ set rule turtle-rule
set color turtle-color ] ]
end
