Help in understand byRef Functions

[jsong55]

I need to constantly work on 2 nested maps

Code: Select all

MapOfReValueSGT, MapOfReValueOthers

I first initialize them here

Code: Select all

MapOfReValueOthers := Map()
MapOfReValueSGT:=Map()
Loop 3
    MapOfReValueOthers[A_Index] := Map()
Loop 3
    MapOfReValueSGT[A_Index] := Map()

Then I pass them into a function that's been defined

Code: Select all

Mtd2Clicked(*) ; from a gui button
{
    Mtd2Fn(&MapOfReValueOthers,&MapOfReValueSGT)
}

The function is defined here

Code: Select all

Mtd2Fn(&MapOfReValueOthers,&MapOfReValueSGT)
{
; some code in between that uses both Map values
}

Problem is when I debug within the function Mtd2Fn it says the maps are not intialized. When I debug the step outside at Mtd2Clicked - they are fine, they are global and initialized.

ur issues have less(in fact, nothing) to do with ByRef and everything to do with the way ur code is structured/scoping

post the full nonworking code, then i can tell u what u did wrong

Probably not really global but read only. Need to explicitly make them global in Mtd2Clicked.
