help in pic Basic Pro "Break statement"

in this code i want to increase duty until Feedback is equal to 3, then to break the loop after feedback is equal to 3, then to take this value of duty which made feedback equal to 3 out of loop and to continue to output this constant duty.
In Pic basic is it possible to use this break statement as in c language, if yes how? If no help me alternative way to solve this problem, thanx in advance

Code:

---

                                *
'****************************************************************
clear
DEFINE ADC_BITS 8
DEFINE ADC_CLOCK 3
DEFINE ADC_SAMPLEUS 50
  ' Duty cycle value (CCPR1L:CCP1CON<5:4>)
Feedback  var word
ADCON1=%00000010
duty VAR WORD  ' Duty cycle value (CCPR1L:CCP1CON<5:4>)

  TRISA = %11111111
  TRISB = %11111111
  TRISC = %11111011      ' Set PORTC.2 (CCP1) to output
  CCP1CON = %00001100  ' Set CCP1 to PWM
  T2CON = %00000101    ' Turn on Timer2, Prescale=4
 
 
' Use formula to determine PR2 value for a 1KHz signal,
' 4MHz clock, and prescale=4. (4E6/(4*4*1E3))-1=249

  PR2 = 249      ' Set PR2 to get 1KHz out
       
' Use formula to determine CCPR1L:CCP1CON<5:4> value for
' ends of range 20% to 80%.  (249+1)*4*0.2=200 (20% value)
' (249+1)*4*0.8=800 (80% value)

  duty = 0      ' Set duty cycle to 0%

mainloop:
  adcin 0, feedback           
  CCP1CON.4 = duty.0  ' Store duty to registers as
  CCP1CON.5 = duty.1  ' a 10-bit word
  CCPR1L = DUTY >> 2
  duty = duty + 1    ' Increase duty cycle

' Since the total sweep of duty is 1000 (1000-0) and
' we are adding 1 for each loop, that results in 60
' steps min to max. 1 second divided by 1000 = 1mS           

  Pause  1
            ' Pause 1/60 of second

  IF (feedback => 3) Then
'      *****break the loop****
      endif
   
  GoTo mainloop        ' Do it forever
   
      CCP1CON.4 = duty.0  ' Store duty to registers as
      CCP1CON.5 = duty.1  ' a 10-bit word
      CCPR1L = DUTY >> 2
     
    End

Use either "REPEAT..UNTIL" or "WHILE..WEND"

BR,
-Gusse-

how about:

clear
DEFINE ADC_BITS 8
DEFINE ADC_CLOCK 3
DEFINE ADC_SAMPLEUS 50
' Duty cycle value (CCPR1L:CCP1CON<5:4>)
Feedback var word
ADCON1=%00000010
duty VAR WORD ' Duty cycle value (CCPR1L:CCP1CON<5:4>)

TRISA = %11111111
TRISB = %11111111
TRISC = %11111011 ' Set PORTC.2 (CCP1) to output
CCP1CON = %00001100 ' Set CCP1 to PWM
T2CON = %00000101 ' Turn on Timer2, Prescale=4


' Use formula to determine PR2 value for a 1KHz signal,
' 4MHz clock, and prescale=4. (4E6/(4*4*1E3))-1=249

PR2 = 249 ' Set PR2 to get 1KHz out

duty = 0 ' Set duty cycle to 0%

gosub Adjust:'adjust pwm duty cycle routine

mainloop:
GoTo mainloop ' Do it forever

Adjust:'adjust pwm duty cycle routine
feedback = 0 'set to 0 for first pass
while feedback < 3
adcin 0, feedback
CCP1CON.4 = duty.0 ' Store duty to registers as
CCP1CON.5 = duty.1 ' a 10-bit word
CCPR1L = DUTY >> 2
duty = duty + 1 ' Increase duty cycle
' Since the total sweep of duty is 1000 (1000-0) and

' steps min to max. 1 second divided by 1000 = 1mS
Pause 1 ' Pause 1/60 of second
CCP1CON.4 = duty.0 ' Store duty to registers as
CCP1CON.5 = duty.1 ' a 10-bit word
CCPR1L = DUTY >> 2
wend
return

End

thanx in advance -Gusse and Dave for ur suggestion, am taking some time on what you sugggest then i will come to you when i meet any difficulties
