Ted, Thank you for your reply to my question. As to being an MS product, well, if you do your comparison with the assumption that MS never existed, I really don't know where we would be today. It's alway easy to see the "defects" and the things we would like to have and don't, but, it's not possible...

On my "stadard" keyboard, I was able to stop an endless loop by pressing Ctrl+Scroll, and also Ctrl+NumLock. Perhaps your laptop will also stop your program. If not, try Ctrl+some other key. It just might work!

Ted, is there a way to make "Save as text, readable etc." the default? It seems one should be able to, but, how?

Right! To read from a file, one must tell QB to first open it. Assuming your file, STDIN, has no extension and is in the same directory as qb.exe, here's how: OPEN "STDIN" FOR INPUR AS #1 WHILE NOT EOF(1) 'allows reading all the lines in the opened file LINE INPUT #1, A$ 'assigns the first line to t...

Ted, your MOD solution is good for integers; so is AND; so are others. I've said it befor, and I will now repeat it. Ted, your knowledge in electronics and in qb is very much appreciated by me and, I'm sure, by many others. Why do you have to ruin it by picking on people? I know that it amuses you, ...

Hi, Moneo: The reason I used AND in my code was to show that the result obtained by using AND, as well as a number we know has a small remainder in QuickBASIC (in ALL qBASICs?). For the case of testing integers, AND works fine, giving the correct mathematical result. However, it does not give the co...

Hello,, Moneo! Here is another quirk I find in QuickBASIC 4.5. I ran the code in G-W BASIC, and got Odd. 0, ODD, odd, 0, A is odd. I ran the code in QuickBASIC and got Odd, -1.734723E-18, EVEN, even, -1.734723E-18, A is odd. So, the value that qb returns for 5 ^ 2 is not truly the integer 25, since ...

Roy and Ted's explanations make some sense to me, but, why don't the following three FOR/NEXT loops give the identical exaxt values for ALL three cases? Notice that the first one gives exact values for 1 through 2.7, the second one for 1.5 through 2.5, and the last one for 2.3 through 2.7 CLS PRINT ...

O.K. Then why does this give a small difference for ALL values of i for the first difference, and, except for i = 1.4 and 1.8, gives 0 for all other values of i for the second difference. ALL the values of i are single precision. FOR I = 1 TO 2 STEP 0.1 A = I^2 PRINT I, A-I*I, I^2 -I*I NEXT I

Ted, we're still not there. In the code, "FOR I = 1 TO 20", doesen't the vaiable I qualify for single precision assignment? If so, why does the example code in my previous post not give A 0 for "PRINT I ^ 2 - I* I" for all valuies of I? It does, but only for values of I of 1, 2, 3, 4, 6, 8, 12, and ...

In the following code, I didn't actually use the ! to assign the single values, just the second line, "A = I ^ 2", and QB acts the same as in your example, but "I ^ 2" doesen't. Why? Is it that the default for any variable is single prexision, so that "A = number" will automatically make "number" a ...

That was good, Tec. I didn't understand your last part, the one about variable = 10 ^ 2 ' undefined single variable Then substitute that value to get rid of the small accuracy problems with Double values. I entered" PRINT 10 ^ 2 - 100 and I got the remainder, -6.928894E-18 indicating that 10 ^ 2 doe...

Try: IF number/2 = INT(number/2) THEN While a number may APPEAR to be difisible by two, it may have a very small error, and not be truly an even number. For example, it we test the result of 10 ^2 against 100, we get a remainder, thus, the second line below returns, "NOT AN EVEN NUMBER", since the n...
