Hi Kyle

One of the ways to handle it is to create a global Handle in the oApplication

For example:

Code:
Object oApplication is a cApplication
    //Set WorkspaceName to CURRENT$WORKSPACE
    Set pbEnterKeyAsTabKey to True
    
    Property boolean pbLL12Registered
    Property Handle phChildWorkbook
    
    Procedure OnCreate
        Send DoOpenWorkspace CURRENT$WORKSPACE
        Set pbPreserveEnvironment to False
    End_Procedure


//    Set ModuleName    to 'ProgramName' // Special module name.
//    Set HelpName      to 'HelpName.hlp'// Please provide the name of your Windows help file.
End_Object


Handle hAppWS
Move (phoWorkspace(ghoApplication)) to hAppWS
Then I will move the object file handle to that global variable. Often you could do this in the Activate procedure, but you can probably find other ways as well

Code:
   Procedure Activate
        Handle hObj hClientWorkbook hChildWorkbook hCrisis
        Forward Send Activate
        
        Set phMenu of hAppWS to (Self)
        Get phClientWorkbook of hAppWS to hClientWorkbook
        If (hClientWorkbook=0) Begin
            Get Object_Id of (oClientWork(Client_Area(Self))) to hObj
            set phClientWorkbook of hAppWS to hObj
        End    
        Get phChildWorkbook of hAppWS to hChildWorkbook
        If (hChildWorkbook=0) Begin
            Get Object_Id of (oChildWorkbook(Client_Area(Self))) to hObj
            Set phChildWorkbook of hAppWS to hObj
        End    
        Get phCrisis of hAppWS to hCrisis
        If (hCrisis=0) Begin
            Get Object_Id of (oCrisisCall(Client_Area(Self))) to hObj
            Set phCrisis of hAppWS to hObj
        End    
        
        
        
    End_Procedure
Then you can access it from any other object:

Code:
// popup an edit panel for the selected row.
                Function EditRowPopup Returns Boolean
                    Boolean bOk
                    Handle hWorkbook
                    Integer iInternalNo iClient iRet
                    //tTableDataLine DataLine
                    //Get SelectedRowValue of oName to DataLine.sName
                    Get SelectedRowValue of oChildNumber to iInternalNo
                    //Get SelectedRowValue of oStatus to DataLine.iSize
                    Get piClient to iClient
                    
                    Get phChildWorkbook of hAppWS to hWorkbook
                   
                    If (iClient>0) Send pLoadChild to hWorkbook iInternalNo
                    Else Begin
                       Function_Return bOK
                    End
                    Send pPopulateGrid to (Self)
                    
                    
                    
                    Function_Return bOk
                End_Procedure
