A basic problem in AutoIt3

[gil900 83]

Not much to say ..

To save words simply try to run this code:

call("test")

Func test()
$test = "working"
Call("func1")
EndFunc

Func func1()
MsgBox(4096,"test",$test)
EndFunc

The variable $test is not saved if it is in the function.

This basic problem prevents me from continuing to program what I want.

I have the variable will remain even after the exit from the function ..

I do not understand why the system works that way ..

You need to Return the variable if you want it available outside of the function.

$value = _test()
_func1()

Func _test()
$test = "working"
Return $test
EndFunc

Func _func1()
MsgBox(4096,"test", $value)
EndFunc

why the:

$value = _test()

_func1()

?

[kor 5]

Because that's the way you run functions.

[gil900 83]

Ok

Possible to do it with the Call() ?

[kor 5]

Yes. But with call you are limited. You can't use ByRef which for me personally is a deal breaker.

I would learn to call functions the way everyone else does though. it will make getting help on the forums much easier.

I've never seen anyone use the Call before.

Why add another variable?

It also works:

$test = test()
Call("func1")

Func test()
$test = "working"
Return $test
EndFunc

Func func1()
MsgBox(4096,"test", $test)
EndFunc

It's only with one variable.

There is another situation that I have to show.

[gil900 83]

this is the new problem:

$a = test()

$v1 = 5
$v2 = 10

for $i = 1 to $v1 step 1
test()
Next

Func test()
for $o = 1 to $v2 step 1
$a = $o
Return $a
test2()
Next
EndFunc

func test2()
for $q = 1 to 20 step 1
msgbox(4096,"working",$a)
Next
EndFunc

I tried what you said but in this case it did not work

$a = test() ;$a will equal the first thing test returns

$v1 = 5
$v2 = 10

for $i = 1 to $v1 step 1
test()
Next

Func test()
for $o = 1 to $v2 step 1
$a = $o
Return $a ;the function returns the value $a is currently set to in this case the loop is pointless and will always return the number 1
test2() ;this never executes
Next
EndFunc

func test2()
for $q = 1 to 20 step 1
msgbox(4096,"working",$a)
Next
