For / f parameter usage:

1.1 the space around the "delims=*" equal sign makes sense.

1.2 the default parameter of option is "delims=", so if you read a line of parameters, you will not read them if you encounter spaces. If we need to read the whole line, we can make the parameter of delims the last character.

Summary of set parameters:

2.1 set I = "abc" assigns a string to I. Such as:

Set I = "abc"

Echo% I%

If% I% else = "abc" (echo equal to abc) else (echo don't equal to abc)

2.2 set / axia123 assigns a number to I

2.3 set / Pi = Please enter a value for I. The default input is a number. If you want to use it as a string, you need to add "" on both sides of I when you need to call variables, such as:

3.3 set / p i=Please told me your options:

Echo% I%

If "% I%" = "a" (goto addpatch) else (goto installpatch)

: addpatch

Echo add patch

Goto: eof

: installpatch

Echo install patch

Goto: eof
