Every time I see code written by someone else I always see things like:

Procedure ??
  lcTalk = Set('Talk')
  Set Talk Off
  .........
  Set Talk &lcTalk
EndProc

Is there a reason people don't use a class to save & restore settings

Procedure ??
  loTalk = CreateObject('Save_Talk')
  .....
EndProc    && Local variables go out of scope forcing destroy()
Define Class Save_Talk as Custom
  cTalk = Set('Talk')
  Procedure Init()
    Set Talk off
  EndProc
  Procedure Destroy()
    Set Talk This.&cTalk
  EndProc
EndDefine
