The idea for this puzzle sprang from this post of bobbym's. It underwent some refining on that thread, and here's the final product...

Find Piman's date of birth, using these rules:

- His DOB is an 8-digit number either in ddmmyyyy or mmddyyyy format;

- Piman was born since the turn of the last century, on a Thursday;

- His YOB appears in the first 100000 decimal digits of pi;

- The YOB's starting position in that pi range iterates to 1...as per the following example:

*eg: The starting position of YOB 1839 is 9323...whose starting position is 14...whose starting position is 1*

*Note: Ignore the "3." preceding the decimal digits...so 3.14159 becomes 14159 and 5's starting position is 4*;

- Iteration searches remain within pi's first 100000 decimal digits.

Hi Bobby,

I've set the rules out in list form, for clarity's sake.

Off to work now...

Hi phrontister

See you soon!

Hi,

I changed the "He could still be alive today" rule to "Piman was born since the turn of the last century".

This will help anyone trying to solve the puzzle in Excel, because their Weekday function only kicks in from 1/1/1900.

The solution remains the same.

Hi;

That is okay with me.

When you mentioned that Excel has a weekday command it finally occurred to me that M might have one too. Sure enough here it is. Would have saved some time.

Hi Bobby,

LB doesn't have the WEEKDAY function, but I googled it and found a good one that I included in my solution.

Hi;

You have a 64 bit OS?

Then the QB64 is for 32 bit machines too?

I suppose it must be...no hiccups at all on mine, and it's nice and speedy.

There's some discussion about 32- & 64-bit stuff at the QB64 site here. Just type "64 bit" into the search box. I had a verrrrry quick browse just now, and took nothing in.

Sorry, but I don't know much about this at all.

I found this in a Wikipedia article here:

QB64 (originally QB32) is a self-hosting BASIC compiler for Microsoft Windows, Linux and MacOSX, designed to be compatible with Microsoft QBasic and QuickBASIC. QB64 is a C++ emitter, which is integrated with a C++ compiler to provide compilation via C++ code and GCC optimization.
