15.2.5 Conditional block repetition ($WHILE)
$WHILE <condition>... $ENDWHILE
The following parameter is defined in this instruction:
While the condition is true, it executes the blocks contained between
$WHILE and $ENDWHILE. The condition is analyzed at the beginning
of each new repetition.
The $BREAK instruction lets ending block repetition even if the stop
condition is not met. The execution of the program will continue at the
block after $ENDWHILE.
The $CONTINUE instruction starts the next repetition even when the
current one has not finished. The blocks program med after
$CONTINUE up to $ENDWHILE will be ignored in this repetition.
<condition> I t m ay b e a c o m p a r i s o n b e t w e e n t wo n u m b e r s ,
parameters or arithmetic expressions whose result is a
number.

N20 $WHILE P1<= 10
N30 P1=P1+1
N40...
N50...
N60 $ENDWHILE
...
While P1 is smaller than or equal to 10, it executes blocks N30 through N50.
...
N20 $WHILE P1<= 10
N30...
N40 $IF P2==2
N50 $BREAK
N60 $ENDIF
N70...
N80 $ENDWHILE
...
Block repetition stops if P1 is greater than 10, or if P2 = 2.
...
N20 $WHILE P1<= 10
N30...
N40 $IF P0==2
N50 $CONTINUE
N60 $ENDIF
N70...
N80...
N80 $ENDWHILE
...
If P0=2, it ignores blocks N70 through N80 and it starts a new repetition at
N20.
