Here's my bat script code:

 
@ echo off 
The set var1=
The set var2=

: aa 
If "% % var1"=="" goto bb 
Set/p var2=please enter the number 2: 

If % % var2==2 (
: bb 
Echo input var1 before: % var1 % 
Set/p var1=please input the value of var1: 
Echo input set after check the value of the 
The set var1 
Echo after input var1 % % 
Echo "-- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -" 
Goto aa 
) 

After the second set the value of var1, echo output is still the old value, but set var1 can display real-time values here

CodePudding user response:

Try this

@ echo off

Echo input var1 before: % var1 %
Set/p var1=please input the value of var1:
The set var1
Echo after input var1 % %
Echo "-- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -"
Echo input var1 before: % var1 %
Set/p var1=please input the value of var1:
The set var1
Echo after input var1 % %
