Nice! Why does ANGLOPOLY work only for polygons up to 24 sides, though?

Well, after icosagon (20 sides), the polygons really don't have any real names. It goes 21-gon, 22-gon, 23-gon, etc. I just decided to stop at 24. I really don't know why...

I noticed that the zip file you uploaded to the archives is new rather than an update of your previous upload. Was that intentional? Also, I noticed that your description was just a link to this thread; I'd prefer a bit more substantial of a description, although leaving the link in addition is fine.

It was intentional. I would like if you could completely remove the previous files, and I'll just keep updating this one. As for the description, I'll try to add something

If you were to re-upload this over the old zip, that would let you keep your downloads and would make everything run slightly more smoothly, but I understand if it's too much trouble.

I don't mind about the downloads. It was only about 50 or so. But I'd just like a fresh start, if you don't mind

I understand, not a problem. I just don't have an automatic way to delete items from the archive.

Are you saying that you're not able to remove items from the archive?

No, I'll do it momentarily, it's just not easy, because I need to go into the MySQL database and remove the file item, then track down the actual zip via SFTP and delete it. I wrote automated tools to do lots of other archives functions, but sadly deleting programs isn't one of them, because I hardly ever have to do so.

Oh, I know what that's like >.<

Ok, well, I'm starting another re-write, prgmFOIL. This prgm executes the First Outer Inner Last sequence. I want the user to be able to type in the entire equation, "(3x+2)(x+4)", and have the prgm return 3, 2, 1, and 4 as values. How could I go about doing this?

First you would get the values inside the parenthesis (and it sounds like you have, from IRC) then you would get the numbers before the X using sub() and inString(). For the numbers after the +, you would do the same but inString(,"+") instead. Some code:
Code:
Str2 holds the string version of the number before the X. Str3 holds the string version for the number after the +. A holds the actual number of Str2, and B holds the actual number for Str3. It expects you to input a string like:3X+2. No ending parenthesis.

The above code didn't seem to work. "BASIC Ex Err:DOM". When I go to prgm, it stops at "sub(Str1,Ans,length(Str1)-Ans)->Str3"

Do you happen to know what Ans was/is when it crashes? Also, what input string?

Well, I replaced Ans with "3" (sub(Str1,Ans,length(Str1)-Ans)->Str3 to sub(Str1,Ans,length(Str1)-3)->Str3) and it seemed to work

This should work instead, I was off-by-1
Code:

Ok, that works. But, I'm asking for the input of two equations at a time. "(3x+2)(x+4)" will be a single string. Possible?

Of course, just sub() and inString() out what you need. For instance, to get the second number before the X, you would do:
Code:
(Should work, if it is off by 1, start adding or subtracting 1 from certain parts. Most likely, if it is wrong, the sub() line is at fault.)

I typed in "(3X+2)" as the string, but it gave me a syntax error. Is there any way to remove the parenthesis from a string?
