Re: Generating Random numbers to conform a distribution

Try rolling 2 six-sided dice. 7 is the number that appears the most so it’s at the middle of the curve, while 2 and 12 are at the ends of the distribution. Roll the dice multiple times to generate a distribution. Now simulate rolling the dice with random numbers in LC the same way. Now conduct

Re: char as word boundary

Still jumping without thinking… If native char 202 or unicode char 202 is a word boundary in Windows it is a real bug — but is that the case? Native char 202, a non-breaking space, should (or maybe shouldn’t) be a word boundary in Mac - the docs say word boundaries are space, tab and return. W

Hmm. I jumped without thinking…I was thinking if unicode char 2029 which is the paragraph separator. Unicode Char 202 is supposed to be Latin Capital Letter E With Circumflex. But 202 is beyond the standard ascii range so the deprecated numtochar(202) will return an extended ascii character dep

Though it is true that “numToChar” and “charToNum” are deprecated, they still live and work the same as always. Old habits die hard, andI still use them. One day I will move on., but the original issue has not changed. Craig > On Jun 7, 2022, at 9:01 AM, Jean-Jacques Wagner via use-livecode

Re: use-livecode Digest, Vol 225, Issue 4

Hi Sorry, I ment the number of words. Since numtochar has been depreciated with version 7.0, the closest would be now numtonativechar. However with numtonativechar () for the words boundaries the following chars number “09,10,11,12,13,32,202” are used. Therefore a feature has been depreciate

I have never had any issues with the number of parameters that can be passed to a custom handler. Nor any issue with “seeing” them all in the debugger. I would say that the largest number of params I ever sent was about 15. Craig > On Jun 6, 2022, at 4:08 PM, Bob Sneidar via use-livecode >
