There are instructions included in the 34S for doing this kind of thing easily:

Code:

LBL A

LocR 08

STOS .00

...

X<> .00

STO L

RCLS .00

RTN

Not as good as XROM's xIN/xOUT but this version will nest and you've got the input value in a register for easy access and LastX is handled correctly. Not bad for five steps.
