Error 3353 - Structure too complex 

Keywords:      Error 3353 - Nesting of Structure too complex

Question:

I am using the following code to choose which application to run: 

;===========================================
ButtonPushed=Dialog("XcelleNet")

if buttonpushed == 2 then goto Quit

if RADIO == 1 
    Run ("c:\nodesys\nodecomm.exe", "")
else
    Run ("c:\nodesys\winauto.exe", "-d 3 1")
endif


:Run_Session
if AppExist("winauto.exe") == @TRUE
	timedelay(15)
	goto Run_Session
endif

:Done
if RADIO == 2
	WinActivate("IBM")
	sendkeysto("IBM","!{F4}y")
	Run ("c:\nodesys\nodecomm.exe", "")
endif

:Quit
In certain undocumented times I get the following error: 
 
	3353 Nesting of structures too complex
	"if AppExist("winauto.exe") == @TRUE"
Any ideas why?

Answer:

It's those goto's. They are naughty. Read about them in the manual.

Take out the "goto Run_Session" in your if/endif loop. Try... 


;==============================================
ButtonPushed=Dialog("XcelleNet")

if buttonpushed == 2 then goto Quit

if RADIO == 1 
   Run ("c:\nodesys\nodecomm.exe", "")
else
   Run ("c:\nodesys\winauto.exe", "-d 3 1")
endif

:Run_Session
while AppExist("winauto.exe") == @TRUE
timedelay(15)
endwhile

:Done

if RADIO == 2
   WinActivate("IBM")
   sendkeysto("IBM","!{F4}y")
   Run ("c:\nodesys\nodecomm.exe", "")
endif

:Quit

Nesting of Structures Too Complex or Deep

Related Question:

I have what I think to be a simple if..then statement and when I run the script I get ERROR 3353: STRUCT ERROR NESTING OF STRUCTURE IS TOO COMPLEX. Here is a sample of the code: 

;=======================================================
:wait4child1
name = char2num("Wait (Cancel to halt)")
char = wingetactive()
active = char2num("%char%")
if name == active then 
sendkey("~")
else
gosub wait4child1
return
The script waits for a program to finish processing. When the program is finished it displays a message box with the title "Wait (Cancel to halt)". So I store the name of the box in a variable and then convert it to a number so that I can compare it to the real thing when the message box is displayed.

Why am I getting this error??? Thanks in advance for any help.

Answer:

  1. The big problem is the gosub. So it works once. Then the entire loop is GOSUB'ed again, but no return. One structure level is used up. Then again, and another level is used up.

  2. The if/else does not have an endif. Mayhaps you are getting confused betwixt the single line if/else and the multiline if/else/endif.

  3. Since you posted the code, and it was real short, I re-wrote it for you. See below:

    ORIGINAL CODE: 

    

:wait4child1
name = char2num("Wait (Cancel to halt)")
char = wingetactive()
active = char2num("%char%")
if name == active then 
sendkey("~")
else
gosub wait4child1
return
    MODIFIED VERSION: 
    
:wait4child1
while 1
   name = char2num("Wait (Cancel to halt)")
   char = wingetactive()
   active = char2num(char)
   if name != active then continue
   sendkey("~")
   break
return
