如果GTR / LSS运营商在批量

问题描述

我有一个使用 GTR / LSS 运营商越来越大的批处理文件。问题是，在如果语句只允许我进入某些值。在下面的示例，在2，3或4的值输入将返回值过高。

I have an increasingly large Batch file that uses GTR/LSS operators. The problem is that the if statements only permit me to enter certain values. In the following exemplar, typing in values of 2, 3 or 4 will return "Value too high."

:char_intb
set char_points=30
set /a limit=!char_points!-3
set /p char_int="How many points for intelligence? "
if "!char_int!" GTR "!limit!" echo Value too high. && goto char_intb
if "!char_int!" GTR "!char_points!" echo Insufficient points. && goto char_intb
if "!char_int!" LSS "1" echo Select a value greater than or equal to 1. && goto char_intb
set /a char_points=!char_points!-!char_int!
echo You now have !char_points! remaining.

有别人。至于我测试过，它似乎只允许我键入0或11

There are others. As far as I've tested, it seems to only allow me to type 0 or 11.

set /p char_month="Month (0-11): "
if "!char_month!" GTR "11" echo Enter a value between 0 and 11. && echo. && goto last_char

我在哪里去了？

推荐答案

不要使用双引号！char_month！ GTR十一对于数字比较，在这种情况下 CMD 会做的字符串比较。这应该工作：

Do not use double quotes "!char_month!" GTR "11" for numeric compare, in this case cmd will do a string compare. This should work:

@ECHO OFF &SETLOCAL
:last_char
set /p "char_month=Month (0-11): "
if %char_month% GTR 11 (
    echo Enter a value between 0 and 11.
    echo.
    goto last_char
)
ECHO %char_month%
