I am trying to create a batch file that will give me a list of games, and then i could execute one of them by typing the number associated with that game.

It works with the command prompt but i am having problems with dosbox. In dosbox once i execute the batch file I cannot type a number into the answer line. (I attach images)

1Title = "Game List"
2@Echo off
3CLS
4mode con: cols=40 lines=15
5:MENU
6cls
7Echo Choose a game from the list:
8Echo.
9Echo [1] Comanche
10Echo [20] Duke 3D
11Echo.
12set /P menu=:
13if '%menu%'=='1' "D:\\dosgames\COMANCHE\COMANCHE.exe"
14if '%menu%'=='20' "D:\\dosgames\Duke3D\Duke3D.exe"

Command Prompt

DosBox

Any help would be welcome. (P.S. I'm a noob at programming.)

Thanks for reading my thread.

DOSBox emulates DOS, not the Windows command prompt. The /P parameter is not supported on SET. Instead, look at using the DOS command CHOICE.

I didn't know that command was only for command prompt.
I did a little research on that command that you told me and I almost got it.

Now I am having trouble loading the second choice. So, when I type "1" Comanche:Maximum Overkill comes up, and when I type "2" Duke Nukem 3D should come up, but instead Comanche:Maximum Overkill comes up.......

1Title = "Game List"
2@Echo off
3CLS
4mode con: cols=40 lines=15
5:MENU
6cls
7Echo Choose a game from the list:
8Echo.
9Echo [1] Comanche
10Echo [2] Duke 3D
11Echo.
12CHOICE /C:12 /N Pick A Game:
13IF ERRORLEVEL == 1 GOTO COMANCHE
14IF ERRORLEVEL == 2 GOTO DUKE3D
15:COMANCHE
16cd C:\\COMANCHE\ 
17comanche
18:DUKE3D
19cd C:\\DUKE3D\ 
20duke3d

Thanks Ripsaw for the reply.

Your approach to ERRORLEVEL is not correct. You don't need to use equal signs, and test the error level in descending order because lower levels are true compared to higher ones.

1IF ERRORLEVEL 2 GOTO DUKE3D 
2IF ERRORLEVEL 1 GOTO COMANCHE

Search for examples of how to use CHOICE and ERRORLEVEL, there should be plenty available on the net.

🤣, thank you. I did find an example (http://www.techiwarehouse.com/engine/e1241093 … h-File-Commands), but the noob I am didn't think I had to list the IF commands from higher to lower.

Thank you.

DOSBOX RULES !

Don't even apologize for this... DOS Batch files work so weird... if you test an errorlevel in an IF it actually measures if it is at least that value... makes programming for it a pain in the butt.
