How to exit a program or rather not process further code if a condition is not met ?

Say for example a check for a variable 'a' ?

If a is not equal to (a~= 1) abort the program and do not execute further codes , else continue ?

Thanks,

Tonu

Error should only be used when there is, ehm, an error. To stop the execution otherwise, use return.

I prefer this. Example:

if a ~= 1
  return;
end

The return statement returns control to the program that called the function, it doesn't terminate execution unless called from the top level.

Is there a way to gracefully stop execution within a called function?

Hey I just used the 'error' function , and it is working fine. If any other option , please suggest, Thanks,Tonu

Hi, can you please elaborate this ? In my case I am trying to abort a function that is currently running by setting the flag to false when abort button is pressed in an app designer.
