Re: loop in body of main program

Okay, probably not the nicest bit of code I've ever written, but it 
seems to do the trick:

-----begin loop-demo.rsrc.py-----

     {'type':'Background',

           'statusBar':1,
           'style':['resizeable'],

         'menubar': {'type':'MenuBar',
          'menus': [
              {'type':'Menu',

              'items': [
                   {'type':'MenuItem',

                    'command':'exit',
                   },
               ]
              },
          ]
      },
          'components': [

{'type':'StaticText',
     'name':'StaticText3',
     'position':(10, 45),
     'text':u'environment:',
     },

{'type':'StaticText',
     'name':'StaticText2',
     'position':(10, 30),
     'text':u'known as iteration) in an event-driven programming',
     },

{'type':'Button',
     'name':'stopLoopBtn',
     'position':(115, 125),
     'label':u'Stop Looping',
     },

     'layout':'horizontal',
     'max':10,
     'value':0,
     },

{'type':'StaticText',
     'name':'StaticText1',
     'position':(10, 15),
     'text':u'This program demonstrates a way to control loops (also',
     },
