The HP-41 APPEND command has no name on the HP-42S, but the functionality is there: when you're in ALPHA mode and there is no cursor, just press ENTER.
In program mode, it's the same thing; to create a program line like |-"ABC", do Shift ENTER to activate ALPHA mode, and then press ENTER again to insert the "append" character.
Another thing you'll notice is that some HP-41 commands have different names on the 42S. You can enter them by using XEQ and spelling out the old name, and they'll then be changed to the new name (hold down ENTER after spelling the command to see it change to the 42S spelling, or do the whole exercise in program mode so you can look at the result for more than 2 seconds).
The affected commands are /, *, CHS, DEC, D-R, ENTER^, FACT, FRC, HMS, HR, INT, OCT, P-R, R-D, RDN, R-P, ST+, ST/, ST*, ST-, X<=0?, and X<=Y?.
Commands like STO Z are displayed as STO ST Z on the 42S, presumably to avoid confusion with STO "Z".
Finally, you enter IND commands using the [.] key, not [Shift]. The [.] key brings up a menu where you can choose IND or ST. This takes a little bit of getting used to if your fingers are grooved into the HP-41 way of entering such commands.
