Q: Boolean evaluation

4 posts in this topic

If I have this statement:

if $x>0 and CreateVeryLongFile("filename") then
.
.
.
endif

With $x = 0, will the statement still execute the function CreateVeryLongFile?

I have no idea if AutoIt will or will not execute the function. From my experience/knowledge of other prog language, it should not.

However I am just curious: I have a script that for some odd reason, it is processing the 2nd argument even when the 1st argument is already false.

Probably your $x value is a string not an integer / float. That means $x = "0" is always larger than 0 and if CreateVeryLongFile returns true than the whole expression becomes true.

That must be it!

I just rewrote the function and passed the $x inside the function to see it's value.

True enough it is being evaluated as TRUE!

 

Thanks!

Burgaud,

As you guessed AutoIt uses lazy evaluation of conditions. This is documented in the help file under Language Reference > Operators > bottom of the page.
