(50g) OEIS A014263: Integers with Exclusively Even Digits
For integer input N the programme returns the Nth integer composed solely of even digits.

If "Z5_" means BINT5, then either I made a typo or there's a bug somewhere, because all it does is return 2x for any input x. E.g. Input 153, it returns 306 (contains an odd digit; answer should be 2206).
BYTES on the compiled program returns 75 #48F7h. <0ɸ0> Joe

It works fine for me. I have added a compiled version to my site here:

"Z5_" does NOT mean BINT5. It means ZINT 5, which I could only discover by downloading the copy from Eric's site and disassembling it. The builtin assembler does not know what "Z5_" means, and neither did I. Suggestion: Use HP 50g ASM notation, and include the checksum (which is #FB66h for the above program), when posting System RPL source code. Thanks in advance! By the way, Gerald, I really like the algorithm used here: Convert to base 5, then double that number as a base10 number. Very cool! <0ɸ0> Joe

Sorry, I forget that eg Z5_ is not standard, although Eric Rechlin must use the same tool as me.
As for your 2 suggestions  wilco. Yes, a neat algorithm, thanks to http://oeis.org/wiki/User:Franklin_T._AdamsWatters for his insight.

Z5_ is an unsupported entry  the standard Extable doesn't have it (as far as I know) but there are modified Extable versions that include it along with many other unsupported entries. I'm using the one that comes with Emacs 2.11a and it compiles Z5_ just fine.
