Question on exiting a nested routine

[mirrormirror]

Does exiting a function/for loop/ IF statement before it completes cause any issues? Like using extra memory or other things. I may not be using the correct terminology but look at these examples to see what I mean:

Code: Select all

IF NOT DEFINED myVAR (
   ECHO - error message...
   GOTO :EOF
)

vs

Code: Select all

IF NOT DEFINED myVAR (
   ECHO - error message...
)
IF NOT DEFINED myVAR GOTO :EOF

The FIRST example exits the IF statement before the parentheses are closed - the SECOND one does it AFTER they are closed. Are there any issues with doing it the first way - or any differences between the two methods?

The first method is common and causes no issues that I'm aware of.

If you do it within a loop that is counting, then the loop doesn't return until it has finished. This just means a delay before it exits, and if the loop count is very large then the delay will be noticeable.
