How to conditionally write a call command in a batch file?

Question

I have two lines of a call command in a batch file:

call execute.cmd
call launch.cmd

I need to call launch.cmd if and only if the call to execute.cmd is complete. So, is it possible to somehow establish some conditions?

execute.cmd does not return any value here.

Answer 1

If it execute.cmdreturns an integer than you can use IF commandto check its return value and if it matches what you want, you can calllaunch.cmd

Suppose it execute.cmdreturns 0 if it is successful, or an integer> = 1 otherwise. The package will look like this:

rem call the execute command
call execute.cmd
rem check the return value (referred here as errorlevel)
if %ERRORLEVEL% ==1 GOTO noexecute
rem call the launch command
call launch.cmd

:noexecute
rem since we got here, launch is no longer going to be executed

call execute.cmd
if %errorlevel% neq 0 exit /b %errorlevel%
call launch.cmd
if %errorlevel% neq 0 exit /b %errorlevel%
