undeclared variable error. But variable is declared

[martin]

When I try to run a script I get the following error

>Running AU3Check (1.54.9.0) params: from:D:\Program Files\AutoIt3\beta

+>AU3Check ended.rc:0

>Running:(3.2.9.3): d:\Program Files\AutoIt3\beta\autoit3.exe "Q:\updater\MonItTemp.au3"

Q:\updater\MonItTemp.au3 (2475) : ==> Variable used without being declared.:

DllStructSetData($MonItStruct,$MILineNumber,Number($bb_line))

DllStructSetData(^ ERROR

->AutoIT3.exe ended.rc:1

>Exit code: 1 Time: 6.768

But the variable $MoniItStruct is used many times in the script and even several lines before line 2475 and no error is reported for those occurrences.

The variable $MonItStruct is declared as a Global variable near the beginning of the script.

Presumably autoit3.exe performs its own checks before executing the script because this error is given before the first line of the script is executed.(I inserted a consolewrite line at the strat to test this.)

Does anyone know if this could be related to the file size which is about 2500 lines?

I didn't have this problem when the file was smaller.

Should not matter.

Is the $MonItStruct variable used in an Adlib function or something ?

No, it is used in a fnction which is called often but well after the variable is declared.

But why do I get the error even before the script has started to run, i.e. before the first line is executed?

AutoIt3 only gives the error when the specific line is performed... AU3check does the chekcing of the whole script.

That is the reason why I asked about Adlib or something because au3check will not be able to figure out if a func is preformed and contains variable that aren't declared yet.

Somehow this line is encountere before the variable is declared ...

Is it declared global in a function or at the top of a script?

This is the start of the script

ConsoleWrite('started' & @LF)

#include-once
#include <GUIConstants.au3>
#include <misc.au3>
#include 'D:\Program Files\AutoIt3\beta\Include\dllcallback.au3'
;Opt("MustDeclareVars",1);only for testing this script
;functions added to and called by debugged script
Const $BB_Variables = 30
Global $BBCommand_SingleStep, $BBcommand_stopAtLine, $BBCommand_continue, $BB_lineNum, $BB_functionName
Global $BBState_functionName, $bbState_halted

Global $MonItretval,$MonItpt,$MonIthStub_T,$MonItUpDatePeriod = 200,$MonItpnID1,$MonitStruct,$MonitLinked
MsgBox(0,'$MonitStruct declared','ok')

The Consolewrite on line1 doesn't get executed and nor does the msgbox after the Global vriable declaration so I assumed the script can't be running.

I have now also added a consolewrite line in the function where the problem is and that does get executed!

In that case how is the function called? Why is it called?

No it's a global variable declared as shown in my previous post, outside of any function.

EDIT: I should maybe add that the script itself is not expected to run because it needs another program to exist which it then communicates with. I am only trying to run it by itself it to find out why this error is reported. I get the same error when the supporting program is running though.

I found the problem and it's obvious when you know. The script is a development for a debugger, and the script to debug is included in a wrapper script. The script I was debugging had a function onautoitstart and this code was being debugged before the debugger started working if you see what I mean.

Thanks for you attention Garry and Jos, apologies for wasting your time, I just couldn't understand it, but my debugger told me what was wrong with my debugger.

Debugging a debugger is a bugger.

That's why you (uhm, we) should not use GLOBAL variables. And invest some time in a simple Unit Test strategy..

I know you're right, but for the way I'm trying to make a debugger I need global variables, unless you can tell me a good way to make a debugger without them, and which is fast.

Do you have a new baby Uten?
