Re: valueDiff for arrays?

I'd expect that for two reasons. The first is that all array keys are interred strings (names) so integers need to first be converted to strings and then hashed into a name and then hashed to the slot in the arrays hash table. The second is that byte based version is essentially using a byte se

Interesting. I tried a variation using arrays, and it's three times slower than yours. function get_primes pN local tMroot, tPrimes, tIsItPrime if pN < 2 then return empty if pN = 2 then return 2 put trunc(sqrt(pN)) - 1 into tMroot repeat with i=1 to pN step 2 put 1 into t

Nice improvement ! And I like the variable names much more ... though it could be argued that "tYes", should be called"tMayYetBeAPrime" :-) I now get this version consistently running in 25% of the original time. There is another version which runs about twice as fast - i.e. 14% of the origi

There was an error in the code I posted. It should read "if pN >= 1 then" instead of "if pN > 1" this is the corrected version - function get_primes pN local tMroot, tPrimes, tIsItPrime, tYes, tNo put numtobyte(66) into tYes put numtobyte(65) into tNo if pN < 2

This also helps a bit. Where is Hermann? - function get_primes pN local tMroot, tPrimes, tIsItPrime, tYes, tNo put numtobyte(66) into tYes put numtobyte(65) into tNo if pN < 2 then return empty if pN = 2 then return 2 put 2 into tPrimes put trunc(sqrt(pN))

Dear Swami, I have created this kind of form before: roundrect background and margins between 2 rows. For the background I used my own graphic. The background graphic if present is used by the datagrid library for hiliting the row. I removed it. And for magins, I used a row height upper than the h

It isn't. SuperCard is available exclusively for macOS. There was an effort in the mid-90s to port to Windows, but funding dried up before it was completed so no useful version ever saw the light of day. Toolbook is also single-platform, Windows-only. But most of the others were cross-platfo

Re: Getting Started with DataGrid and another datagrid form

The template is like the group editor. In fact it may actually BE the group editor. The behavior script determines what to do when a row is drawn. I think the thing to understand about datagrids, table or forms, is that for each array element in the data (itself an array) the template is "clone
