(command "rectang" ag_lbcorner (mapcar '+ ag_lbcorner (list ag_progress ag_width 0)))
(command "rectang" (mapcar '+ fsr_lbcorner (list fsr_progress fsr_width 0)) fsr_lbcorner)
(command "rectang" spacer_lbcorner (mapcar '+ spacer_lbcorner (list spacer_progress spacer_width 0)))
(setvar "cmdecho" 1)

我想用上面这段代码画三个大小不同的矩形，但是画出来的矩形确实相同的。盼高手指出问题所在？谢谢了！

关闭补捉再试

谢谢！果然是捕捉在捣乱！

在lisp编程中，通常捕捉要关闭，（command"osmode" 0)
等程序结束前开启
