大家好,最近开始学习macro编程,但是手头没有相关的参考书,就照着help做一些test,下面是自己写的一个小
程序,创建一个箱体,然后通过bool运算给它一个开口以出射光。但是选择文件,并在command键入
o)I/P< (creat_outbox 1550 2500 750 1450 2400) ,点击执行时出现
{;n0/
*** ERROR *** edit:move: application of non-procedure: #[entity 1 3] x_:hii?6V 的错误。而且从tracepro的窗口看,箱体是建立起来了,但是没有移动

如果我按照example中“Toroidal_Mirror.scm”的edit:move语句写程序(如下)就可以正确运行,
h48 bb.p2 (define creat_outbox
fM:80bnL+ (lambda (x_width y_length z_height x_out y_out)
WZ*&@|w (define outbox (insert:block x_width y_length z_height))

/v$]X4 S` P^4'|#~2T 想请教下其中错误的原因 9::YR;NY L>:FGNf^H help中edit:move的
