Write your reply.

assistant: Howdy David,
If you have an eight letter password I think 26^8 is the expression for the
number of possible combinations.  If numbers are included 36^8 is possible.
You have 10 chances out of 36 that a number will appear in each character
position.
The odds are such that at least one number will usually appear.  But because
it's random, eight numbers may occur.
Passwords on BBS's and InterNet usually also include dashes (-), Underlines
(_), periods (.), and some other punctuation characters.
If you wish to ensure a number will occur and also limit how many of them
appear, then the algorythm does get a little messy.
    FOR X% = 1 TO 8
        IF INSTR("0123456789", (MID$(Pass$, X%, 1)) THEN Cnt% = Cnt% + 1
    NEXT X%
LOOP UNTIL Cnt% > 1 AND Cnt < 4
Would be be a way to check.

Hi David,

but...
doesn't this set all elements of the array to zero?
erm, doesn't this use a 'loop' of some kind   :-)
um, what for?
ok, how about using your loop as modified above then
  IF A%(Y%) <> 0 then 220
  A%(Y%)=1
  NEXT
<allowing for any typos, etc>
the numbers will be different and there's no need to sort them as you
simply read each element of the array from 1 upwards and if the element
value is non-zero you print the element number.

          (x3,y3) (x4,y4)  (x1,y1)
Find the length of the perpendicular (y2 - y4). Find the length of the
hypotenuse ->  SQR((x1 - x2)^2 + (y2 - y1)^2).
The length of the perpendicular divided by the length of the hypotenuse
gives the sine of the angle at (x1,y1), which we'll call z. The arcsin
of z in radians is found by:
  ATN(z / SQR(-x * x + 1 + 1E-37))
The 1E-37 seems mysterious but all it does is add a tiny number to the
result to avoid division by zero errors. Seems like a lot of code but
at least we don't need to find the lengths of the other two sides of
the triangle.

Bad idea! That means you're executing RANDOMIZE TIMER over and over
again, which not only wastes time but can actually make the RNDs *less*
like real random numbers!
RANDOMIZE TIMER should be executed just once, near the beginning of the
program, before any RNDs are generated. It should *never* be put inside
any loops, which would cause it to be executed repeatedly.

it happens to hit on a bunch of numbers in the right range.
Of course, it is possible to dream up all kinds of variations on the
theme. Maybe something like:
RANDOMIZE TIMER
DEF FNR%(X%,Y%) = X% + INT(Y% * RND)
DEF FNC$(X%,Y%) = CHR$(FNR%(X%,Y%))
DIM A%(3,2)
FOR C% = 1 TO 3
   READ A%(C%,1), A%(C%,2)
NEXT
DATA 48,10,65,26,97,26
PW$ = ""
L% = FNR%(6,5)
FOR C% = 1 TO L%
  T% = 1 + (C% MOD 3)
  PW$ = PW$ + FNC$(A%(T%,1),A%(T%,2))
NEXT
PRINT "The password is "; PW$
If I haven't made any silly mistakes, the password will be of randomized
length, between 6 and 10 characters inclusive, and the characters will
cycle among numerical digits, uppercase letters and lowercase letters.
Well, why not?! This is all just an intellectual video game.

-> This is very clever; thanks for posting it!

Write your reply.

assistant: Yes. My first reaction, when I saw it, was that a round-off error could
still give x the precise value that would make the denominator of the
fraction zero. But then I realized that this value would be
(+/-)(1 + 5E-38) (very, very nearly). And there's no way that BASIC can
store a number with that many digits. x would be rounded off to exactly
1. So my imagined problem can't happen.
Another interesting thing is that the order in which the additions are
done is important. The 1E-37 must be added in last. If, for example, the
denominator of the fraction were written: sqr(1 + 1E-37 -x*x), which is
mathematically identical to the original, BASIC would have to hold an
intermediate value of (1 + 1E-37), which it can't do. So the 1E-37 would
be lost. I would be almost tempted to use another pair of brackets:
((1 - x*x) + 1E-37), to make absolutely certain that things are done in
the right order.
However, even after all this admiration, I still feel a bit uneasy about
this trick. I just don't like the thought of deliberately introducing an
error into a calculation, however small. I think I still prefer to trap
out the divide-by-zero possibility some other way.
Each to his own taste.

Of course, it's just the bit from line 270 to 370 that does all the

assistant: Howdy Bruce,
There's a cleaner way of doing it.  If you type:
CONST Ansi = CHR$(27) + "["
It will tell you it's invalid.  Instead, enter:
CONST Ansi = " ["
QuickBasic won't let you use Alt-27 but Alt-32 and up work fine.  Use a text
or Hex editor on the source file that will allow you to change the space to
an Escape.  so you have:
CONST Ansi = "["
If you save this message to a file, you can bring it into QuickBasic as a
document file and cut paste the line above into your source code.  Then copy
the quoted chunk to create what you want for standard ANSI escape codes.
Once you have the first lower 32 character inside quotes, you can copy it as
many times as you want.  It's getting the first one that's sticky.

Yes. I admit it. I used your 1E-37 thingy in line 310.
I still think the other way is better, but this does work.
