Batch - IF statements

Question

I need that if the person typing "c" should run the examples in C + +, if the person type "j" should run the Java examples.

But:

1- Does not recognize when I type “c” or “j”, if I type "j", he makes executeC, if I choose "c" also makes executeC not entering this executeJava. Then changed to a numerical value, where if I type 3 - executeC, if I type 4 - executeJava. So if I type 3 it accesses the directory C:\Portico\portico-1.0.2\examples\cpp\cpp13 and processes executeC, 2- If I type 4 it accesses the directory C:\Portico\portico-1.0.2\examples\java\hla13, but does not run, simply ends.

See what i do in the command prompt

C:\Portico\portico-1.0.2\exec>executePortico.bat main
Choose (J)ava or (C)++: 3
C:\Portico\portico-1.0.2\examples\cpp\cpp13\main.exe
Pressione qualquer tecla para continuar. . .

C:\Portico\portico-1.0.2\exec>executePortico.bat java-hla13
Choose (J)ava or (C)++: 4
C:\Portico\portico-1.0.2\examples\java\hla13\java-hla13.jar
Pressione qualquer tecla para continuar. . .
Terminated - Normal
C:\Portico\portico-1.0.2\exec>

See my code please:

The c/j/3/4 switch is working, as it does different things, so those labels are OK. But the command `C:\Portico\portico-1.0.2\examples\java\hla13\java-hla13.jar` isn't doing anything. Does it work directly from the command prompt? Is the folder correct? — AjV Jsy, Feb 20 '13 at 14:28
Your question is very unclear. Are you asking about the IF statements (as in the title), if so is this just a duplicate of your earlier question: http://stackoverflow.com/questions/14733516/batch-files-checking-arguments Or, are you asking about how to execute the jar file, in which case see here: http://stackoverflow.com/questions/1238145/how-to-run-a-jar-file — Vicky, Feb 21 '13 at 09:55
Please figure out what your exact question is, come up with a simple example that shows the problem, and post that. Don't dump your entire program on us and say "it doesn't work, figure it out for me." — librik, Oct 02 '13 at 01:52

It seems you want to enter J or C to branch, but you were testing for 3 and 4. They would both fail and the code would merrily continue along because there was no other logic to handle incorrect input. Try this segment:

if "%~0"=="" goto usage
if "%~1"=="" goto usage

set /p "language=Por favor escolha a linguagem (J)ava or (C)++: "

if /i "%language%"=="C" goto execC
if /i "%language%"=="J" goto execJ
echo incorrect input - quitting
goto :EOF
