Logic Problem? Left bound > Right bound.

[chrispminis]

Alright, I'm working on a text calculator, that was described here earlier. Currently I'm working on procedures that identify and prioritize certain symbols according to PEDMAS, and i just finished that. I just started working on a procedure that identifies numbers. I have managed to detect where numbers start and end, using my symbol markers... But the problem lies, when I attempt to use my custom strreal function to translate the numbers value, I get the error. Left bound of substring exceeds right bound by more than 1. The problem I think is just my logic, but I can't figure out my problem. If you need an explanation as to what the program as doing at that moment just ask. Well, run it and tell me what I did wrong.

Where is the code?

What are u taling about?

Your error appears to be here:

code:

if symbol (j).sused then       number (i).nend := symbol (j).smark       exit    end if

Your problem lies in your assignment of .nend, which apparently never has that clause initiate it! Try it, echo an error message in an else condition to that clause and it should pop up quite frequently.

Also, notice the reformat I did of the code (very minor).

code:

if symbol (j).sused = true then    % condensed to    if symbol (j).sused then

This is possible due to the boolean nature of said variables.

Eum.. not sure exactly what you're talking about... but.. after a good (not really but still sleep is sleep) night's rest, the problem resolved itself. It turned out i was defining an invisible number past the last symbol, and since the invisible thing after that had a value of zero it was smaller. Instead I have another problem, but after a period of debugging ive isolated the problem. It lies within my emulated strreal function. The problem is that, if you'll see the test output at the end where stringy is a 7+ digit number, the first output works fine, but the second value returned also includes the first one? Try it with different combos and you'll see what I mean.

code:

var stringy : string var number : real := 0 var mark : int var dec : boolean := false function stringreal (str : string) : real     mark := index (str, ".")     if mark > 0 then         dec := true     end if     for i : 1 .. length (str)         if str (i) >= "1" and str (i) <= "9" then             number *= 10             number += (ord (str (i)) - 48)         end if     end for     if dec = true then         number := number / (10 ** (length (str) - mark))     end if     result number end stringreal get stringy : * put stringreal (stringy (2 .. 4)) put stringreal (stringy (5 .. 7))

Huh? Where is the code? I cant see it!

[chrispminis]

Um, either you're insane or I am, but since you have the history of being mentally unstable in this thread, im assuming its you. I see it fine.

[MysticVegeta]

I am not joking, I cant see the attached file (if there is any)

[Clayton]

either:
1)ur insane
2)ur blind
3)ur dumb
4)ur being an idiot
5)the initial post has the entire program
6)3 posts above this there is the problem area of his coding (which i cant find out is wrong with it btw) which is causing the problem

Either you truly are insane, or else something is blocking it on your end, since it definately works.

As seen here:

[MysticVegeta]

Gandalf, I see the one you posted but I still cant see anything in his post. I am not idiot =\ but I am insane Honestly guys, I dont see that attachment

maybe chrispminis set an IQ filter so that people with IQ less than 110 arent allowed to look at his code

[Delos]

Then how can you see it dodge?
/me grins...then sidesteps as a series of defective Radeons are thrown at me.

[chrispminis]

Lol, well dont worry. It was stupid, i just forgot to set it back to zero

God shalt punish you! Thou shalt not make fun of a person with reduced mental mobility.

Ok, am i supposed to say it works now cuz it doesn't
