我正在尝试编写一个循环，它将生成一组可在 probsoln 包中使用的随机变量。
我想做一个循环来生成 A、B、C 等。这次考试会有很多问题，我更愿意不单独定义每个问题。然后我想将这些数字传递给选定的问题。我尝试过使用该lcg包，但我认为该包可能存在一些兼容性问题probsoln。
这是工作代码（不含循环）：

任何意见或建议都将不胜感激！我很抱歉在序言中提到了所有这些包，但我以后的问题需要它们。
谢谢您的帮助，但是现在我试图通过在 enumerate 下添加一行将数字传递到随机选择函数中：
\item \selectrandomly{ac-ma}{1}{\myrandomC}
不幸的是，它不愿意接受我的论点，并且我不断收到此错误：
Problem `AC.MA:SYS' (in data base `ac-ma') requires 1 argument(s).
Please specify (e.g. {12}):
我需要将输入包装到某些东西中吗？我尝试使用 \thisproblem 和 \foreachproblem，但总是出现相同的错误。
@grames，我现在正在使用 \esami 包，并尝试从 test1 文件中提取一组随机问题。查看文档，似乎适当的命令是 \estraies[3]{test1}{beta}。然后我会将问题：beta1、beta2 等传递到 \esercizi{beta1,beta2,beta3} 命令行。不幸的是，我似乎做错了什么，因为我一直收到以下错误：

@grames 好的，很高兴知道。我还没能让它工作，但我会继续尝试。我还有一个问题。您的包使用 PSTricks 包来处理图形，根据文档，它应该在工作区空间中。我已将选项更改为 autostopon，但我尝试生成的图形仍然不起作用。我希望所有问题都不会造成麻烦，但我正在尝试在提交问题之前通读文档和示例并尝试代码。这是我正在使用的代码，首先是问题文件。eachtest.tex

答案1
由于您已经在使用 TikZ，因此可以使用模块random()的功能；在 中给出一个随机实数，在 中给出一个整数，在 中给出一个整数。然后将得到的随机整数（用伪随机替换所有随机词）保存到宏中...pgfmathrandom()[0,1]random(x)[1,x]random(x,y)[x,y]\myrandomA,\myrandomB
我还删除/修改了一些包声明，因为有些包声明会加载其他包声明等，并使用 filecontents 包进行ac-ma.tex动态创建。

然而，这个问题似乎是错误的，因为无论如何答案似乎都是零。

我们在 esami 包中使用 fp 和 random 解决了类似的问题。您可以在以下链接中查看 esami.sty 文件中的宏https://www.dropbox.com/sh/0t92kehukgafni5/0Mi0qsYLlR
