If all controls are direct controls of your form you could loop using controls collection, check if that method is defined on control, call the method and if returns false exit loop. Something like:
for each oControl in thisform.Controls
 if PemStatus( oControl, 'myMethod', 5 ) and ;
    lower(PemStatus( oControl, 'myMethod', 3)) == 'method' and ;
    !PemStatus( oControl, 'myMethod', 2)
    if !oControl.myMethod()
       exit
    endif
 endif
endfor
For a sample doing that on selected controls no matter how deep they are check foxyclasses' udfObjCollector ExecAll() sample.
