『楼主』: STRINGS 的语法和作用，麻烦各位点评。呵呵！！使用 LLM 解释/回答一下

上次经过Climbing的指导，终于清楚了STRINGS的强大功能。小弟手头没英文字典，所以只能借助翻译软件，总算把STRINGS的一些子命令的用法搞清楚了，具体请看下面的介绍。由于小弟不懂E文，所以有错或漏的，请各位能帮忙指出并补上。谢谢！！
STRINGS是个很好的批处理增强工具，功能很多，如字符操作，文件操作，内存操作等,并可将值输出到目标变量中。可以使用DOS提示符下输入STRINGS /?查看其所有的使用参数。

再次感谢 Climbing ! 各位喜欢要顶哦!!! 呵呵!!!

Last time, with the guidance of Climbing, I finally understood the powerful functions of STRINGS. I don't have an English dictionary at hand, so I can only rely on translation software to finally figure out the usage of some sub - commands of STRINGS. Please see the following introduction specifically. Since I don't understand English, if there are any errors or omissions, please help point them out and supplement them. Thank you!!

STRINGS is a very good batch processing enhancement tool. It has many functions, such as character operations, file operations, memory operations, etc., and can output values to target variables. You can enter STRINGS /? in the DOS prompt to view all its usage parameters.

STRINGS/? (View the list of sub - commands of STRINGS)

The following is the list of sub - commands of STRINGS:

MASTERVAR LOCALVAR TRUEVER FILES LASTDRIVE CODEPAGE
COUNTRY BIOSDATE GETKEY LOCALENV MASTERENV ADD
SUB MUL DIV AND OR XOR
NOT CONVERT PEEK POKE IN OUT
