Programs / Re: self referencing programs with self modifying capabilities...
« on: May 08, 2019, 12:09:45 pm »
what if I read the executable in with another program, add the needed date to the program which is designed to look for it, and voila! that might work? IE edit the program with another program as if it was a just a file on the computer... then next time that program runs as in actually runs then it should be able to read those bytes you just added, but if you mess up on that adding part and accidentally run the program before you make the necessary modifications that could be very bad...also you should make the program to be sure it will end at it's end by using a system or end or exit command so it does not run the data that you added or will add at the end of the actual program..!!! failure to do so might be bad.

YEs thanks that program for calculating pi uses the Gauss-Legendre algorith also known as Gauss - Euler or Brent-Salamin or Salamin-brent (named after the inventors who came up with this method) with this algorythm pi was calculated to 206,158,430,000 decimal places and the results were checked with Borwein's algorithm, (sept 18 - 20 1999 was when the calculation took place.) awesome ha??

Programs / self referencing programs with self modifying capabilities...
« on: May 08, 2019, 11:44:22 am »
Is it possible to create a program that has a string or value in it that it saves with the program itself that changes every time the program is run?? as in it saves it IN THE PROGRAM ITSELF after the executable part of the code, and then can change it every time it is run, I have some ideas for using this kind of functionality, also the program should not ever actually run on over or whatever the part that it changes, and should be invisibly attached to the program itself, and not as a separate file... can this be done?... like I was thinking maybe have some data attached to the end / at the end of the program after the program is compiled to an EXE that the program would then be able to look for and find, by scaning to the end of the program then rewinding by a certain number of bytes, as the data added would be a specific number of bytes long like say 32 bytes... can this be done??

oh the invalid name problem was fixed, it was that I was trying to pass an argument where the program was not expecting an argument to be passed, I hope it did not "break" the program.. it is a very delicate random number generator.

Thanks a lot !!! It must have added that sometime later as some sort of a glitch that happened, program works fine now!!, give it a try..It does need the added functionality of letter the user look for and browse files and choose a file to encrypt / decrypt etc... but it is a fine start! thanks for fixing the problem , I would have never guessed that it was an argument thing like that, I wonder if the argument was needed for the program to work correctly or not, I will have to review my programs inner workings, flow chart it have tests done for randomness etc... lot of work still needs to be done, but thanks!!!, thanks a lot!!

I tried looking at that it hurt my eyes.. it is overly complicated, isn't there a simpler way of using really big high precision numbers??
I need a much simpler way.. something like BigNumAdd$(a$,b$) where a$ and b$ are strings that represent NUMBERS and that can INCLUDE a decimal point and / or a SIGN (-) isn't there something like that in Qbasic? there should be all the math functions built in to QB64 like this it would make life so much easier for us all, native big decimal support in native Qbasic, what a NOVEL IDEA THAT WOULD BE HA?? ALSO please fix/restore the ability to have subroutine programs without us getting "invalid name" errors PLEASE!!

what I need is quadruple 256 bit floating point precision math support in qb64... that would make things simpler for me... in other words to support a 256 floating point number, I know that's a lot of bytes for a number, but I think it would be great for mathematical accuracy and all...

the above program generates the value of Pi to the maximum precision of double precision numbers in just 3 iterations... is there any way you can have a value that you can add multiply and raise to a power or root or divide etc that would have more precision, like say 2X the precision or perhaps even an ungodly 10X or 1000X the precision that can be easily implimented? what can I say I am obsessed with precision... thanks in advance.
