cond故障
我不知道为什么，但在这段代码中忽略了cond。其想法是将所有页码设为三位数，即001、020、100等。(setq sheetnumber 1)
(foreach tab (_layoutlist)
(setq row 0)
(setq column (+ column 1))
(princ "Test 1\n")
(cond
(> sheetnumber 99)(
(setq sheetnumber (itoa sheetnumber)))
(> sheetnumber 9)(
(setq sheetnumber (itoa (strcat "0" (itoa sheetnumber)))))
(> sheetnumber 0)(
(setq sheetnumber (itoa (strcat "00" (itoa sheetnumber)))))
)
(setq sheetnumber (itoa sheetnumber));Remove this when possible.
(vla-setCellValue table column row sheetnumber)
(setq newname (strcat sheetnumber "-" (substr tab 5 50)))
(setq sheetnumber (atoi sheetnumber))
(setq sheetnumber (+ sheetnumber 1))
(setq row 1)
(setvar 'ctab tab)
(setq tab (substr tab 5 50))
(vla-setCellValue table column row tab)
(command "-layout" "R" "" newname)
) 我对你的语法做了一些更正：
(cond
((> sheetnumber 99)(
(setq sheetnumber (itoa sheetnumber)))
((> sheetnumber 9)(
(setq sheetnumber (itoa (strcat "0"(itoa sheetnumber)))))
((> sheetnumber 0)(
(setq sheetnumber (itoa (strcat "00" (itoa sheetnumber)))))
) 如果您还没有这样做，我强烈建议您参考AutoLISP开发人员文档，以了解AutoLISP函数的正确语法、参数和返回。

李，我正在逐渐学习，但我似乎从实际的书籍中学习编程语言比从在线教程中学习要好得多。不知道为什么。你能推荐一本好书吗？ Jjatho，我们都是来学习的，所以更有趣的是知道我对你的代码提出的更改是否是你想要的，以及你是否理解它们。 确实如此。这是我今天工作的全部代码。你的帮助为我想要的行为画上了句号。
