Bernd, you're absolutely correct. These differences are very small, but can really accumulate.

In my Sha functions, even quite small inputs can result in millions of iterations in the inner loops. I found it made a worthwhile difference to use literals instead of constants, and to put functions ...

I could tell you, but then I'd have to kill you

Efficiency, maybe?

As the author of libBinConvert I just benchmarked the getFloatBE() function.

For 1000 calls it took 20 - 25 millisecs on my two year old intel mac, so shouldn't be causing a problem in a 250 millisecond window...

Also, the library was written before we had private functions, but I doubt the speed ...

I think it's simply that for some functions like random(), baseconvert() and the bitwise operators, the engine converts values to 4 byte unsigned integers.

Phil, I don't think it's all that different:

put "value1" into tArray[key1]
put "value2" into tArray[key2]
...etc

which isn't all that much more verbose than the perl example you give.

On the other hand, if you already have, lets say, a comma and return delimited list, you can use the "split ...

You could also have a global array:

If you put this in the script of your field:

on keyDown pKey
if pKey is in "0123456789." then pass keydown
end keyDown

The user will be restricted to entering only the characters listed.

Of course it gets more complex if you want to avoid a leading decimal point, or multiple decimal points ...

I think you need to move the "utf8" declaration into the unidecode call:
The way you had it will translate a string from utf8 to whatever your system's encoding is.

My guess is that 0e36758 is a interpreted as a number, while "3*3" is an expression.

When you fill in the field with the list of files, you could store the path to the folder as a custom property of the field, and then prepend it to the file name when it is clicked.

assume that this is in the script of the field:

on ShowFiles pFolder
set the directory to pFolder
put the files ...

Here's a shorter (though not necessarily more efficient) way:

on mouseUp
put empty into tArray
repeat until the number of lines in keys(tArray) = 6
put 0 into tArray[random(49)]
end repeat
put keys(tArray)
end mouseUp

Best,

Ken Ray has a great cross-platform handler for getting the MAC address here:

For UUIDs, I'll plug my own pure revolution stack (that uses Ken Ray's handler) for generating type 1,3 and 4 UUIDs, here:

You're quite right - I've actually just uploaded a new version (1.0.1b) in which this is fixed, but more importantly, it now works on Windows with the limitation that it can only see CDs in drive D, and can't cope with "mixed mode" CDs that have non-audio content.

I need to see about getting around ...

I've made a library to get CD track data from FreeDB. It currently uses the pList that OS X builds for each inserted CD to get the info it needs to query FreeDB, so it's OS X only until I figure out how to get the info on Windows and Linux.

It's here:
