in fact nothing is unlogical ... it's the gambas way...

in gambas an error, impossibility, return true... in all the function
that return a boolean

you can imagine to write this in that way

CONST bError as Boolean =True

if .MoveChild = bError then ...

its the same !

in another way it limit the use of the NOT Function keyword




exemple :
if .MoveChild then
  .MoveBack
  if .MoveNext
    .MoveBack
    if .MoveParent then
       .MoveNext
    endif
  endif
Endif
