Re: [Pythoncard-users] loop in body of main program

[Phil E. <ph...@li...>]

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

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

           'statusBar':1,

              {'type':'Menu',

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

                   },
               ]
              },
          ]
      },
          'components': [

     'text':u'environment:',

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

{'type':'Button',
     'name':'stopLoopBtn',
     'position':(115, 125),

     },

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