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,

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

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?

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.
