select key get paired value in batch
select key get paired value in batch
I have a associative array as below
set USERS[johnh]=John Howard
set USERS[moeh]=Moe Howard
set USERS[larryk]=Lary King
When given johnh, it should select John Howard
When given moeh, it should give me Moe Howard
What kind of batch can do this job...
Call Echo %%USERS[%~1]%%
Come on a quick google search shows how arays work in batch. A simple
echo %USERS[johnh]% displays the first array entry. The rest is just some input read and a few if– Paxz

echo %USERS[johnh]%
if
Thanks- I tried to use echo %USER[%johnh%]% it gave me John Howard. Now my issue is that johnh can be a variable. So I tried to set user=johnh then either echo %USER[%user%]% or !USER[%user%]!, none working

Follow @Compo's hint, use
Call Echo %%USERS[%user%]%%– JosefZ

Call Echo %%USERS[%user%]%%
!USER[%user%]! should work. You remembered to enable delayed expansion first, right? Also, I have no idea how %USER[%johnh%]% worked for you; it shouldn't have.– SomethingDark

!USER[%user%]!
%USER[%johnh%]%

Other than using
Call Echo %%USERS[%~1]%%
or
Call Echo %%USERS[%user%]%%
as used in the comments, and despite your continued lack of effort, here's an example batch file:
@Echo Off
Set "USER[johnh]=John Howard"
Set "USER[moeh]=Moe Howard"
Set "USER[larryk]=Larry King"
:Askname
ClS
Set /P "Byname=Please enter your byname: "
Set "Fullname="
For /F "Tokens=1* Delims==" %%A In ('Set USER[ 2^>Nul'
) Do If /I "%%A"=="USER[%Byname%]" Set "Fullname=%%B"
If Not Defined Fullname GoTo Askname
Echo Hello %Fullname%
Pause
