AutoIt just arbitrarily exits a script!

Recommended Posts

I have a 4200-line AutoIt script (3000 operational lines in 72 functions, the remainder comments and whitespace) that I converted from a VBA-like language. I've run into a problem where the AutoIt script just exits the script at a certain point for no seeming reason at all. I've narrowed the exit point at about line 3200 (of the 4200), where a 4-line loop (just 2 lines of active code) occurs. I've put MsgBox's just before and just after this loop: during script operation, the first MsgBox displays but the second does not because AutoIt exited. (Just in case it's helpful, I should also mention that, on one occasion, rather than immediately exiting, AutoIt spuriously jumped to another function and then exited from somewhere in that function.) In addition, when I commented out the 4-line While/WEnd loop and inserted another loop (For/Next), AutoIt similarly exited when it reached that loop.

The only programming reasons I can think of (based on experiences with other programming languages, especially Microsoft's) are the following:

(1) the script is too long or has too many functions;

(2) this (or another or all) function is too long [this one is only 126 lines, including Func/EndFunc] [functions being too long is a common "hidden" Microsoft gotcha];

(3) the While/Wend loop exceeds the maximum allowable depth of loops, If's, Select's, functions calling functions, etc. [nesting depth is the most common Microsoft gotcha that I've run into]; or

(4) the maximum variable space was exceeded.

Anyone know what AutoIt's limits are for these aspects?

And, if there are no relatively low limits, does anyone have any other ideas of why AutoIt might just arbitrarily exit a script? Especially at a loop? This is quite puzzling to me (I can't find any mention of such an arbitrary exit in the documentation), and, because I don't know what's causing it, I haven't the slightest idea of how to work around it (if that's even possible).

Thanks in advance for any help or ideas!

Doubt its any of your shown possibilities.What is the returncode autoit3 exits with?

Are you running a compiled version or from SciTE?

Are you using any DLLCall's ?

None. But your question led to me learning more about AutoIt: I didn't realize there were such things as exit return codes.

Are you running a compiled version or from SciTE?

I was running from SciTE. I tried compiling the code, and that's when the real error showed up (see below). I didn't realize that running from SciTE and running compiled behave differently, at least in terms of error notification.

Are you using any DLLCall's ?

No.

As I mentioned above, running the compiled version of the code turned up the real culprit (and, as you noted, it wasn't any of the four possibilities I had suggested):

"Array variable has incorrect number of subscripts or subscript dimension range exceeded."

I neglected to remember that the original code had 1-based arrays and that AutoIt has 0-based arrays. Once I made that change, everything worked fine. Curiosity question: how come running under SciTE didn't alert me to such a basic error? (I normally run interactively under SciTE to find and fix errors and then, when everything works correctly, I compile my scripts.)

Thanks for your guidance in leading me to find the source of my problem!
