[Octave-bug-tracker] [bug #40392] function parameter not used in while loop correctly

[Michael Godfrey]

Follow-up Comment #9, bug #40392 (project octave):

OK. here is a fact:

octave:23> prob_002 200
Variables in the current scope:

   Attr Name        Size                     Bytes  Class
   ==== ====        ====                     =====  ===== 
  a     argn        1x5                          5  char
    f   x           1x3                          3  char

Total is 8 elements using 8 bytes

y =  10
y =  44
ans =  44
octave:24> prob_002 (200)
Variables in the current scope:

   Attr Name        Size                     Bytes  Class
   ==== ====        ====                     =====  ===== 
  a     argn        1x3                          3  char
    f   x           1x1                          8  double

Total is 4 elements using 11 bytes

y =  10
y =  44
y =  188
ans =  188
octave:25> 
=============================
In the first case x is a char, in the second it is a double.
so the while c<=x %  
is not doing that you thought.

And, John is right.  But this is confusing.
