<< VARS 2 OVER SIZE 1 - SUB ORDER >>

In truth this moves the newest object to the penultimate object in the folder; TOLAST itself is last.

I can take no credit for this elegantly simple tool, I learned if from Joe, but I had to figure it out the hard way, finding a method to accomplish this with the smallest number of bytes. I did find one with fewer instructions, but it was larger.

That's truly a very compact piece of code! And of course you could make it even shorter by removing the "1 -" part so that it would truly move the first item into the last slot, then putting the TOLAST program itself into a library so that you could execute it as needed with any given directory without it having to protect itself.

Actually, I don't mind using and maintaining the var hider, and prefer that it totally hides the objects I feed to it. The occasional editing I have to do to it as I add more targets is easy. It's bigger, of course, but I've never even come close to running out of memory on my 50g for the things I use most often.

I still enjoy discovering new ways to do things on these devices, and continue to be impressed with the versatility of systems that were designed so long ago in "tech years".
