In the MODE catalogue. Press D and you'll get to DBLOFF, you want DBLON which is immediately below.

OK, when you get there, how do you invoke that feature...?

BTW there is no way to programmatically displays the 18 trailing digits in DP mode?

I'm sure a program could be written to display the extra digits:
To get the second 12 digits:
set round to zero mode,
round to 12 digits,
subtract from the original number.
Do this again to get the final 10 digits.

"Round to zero" is round mode 4, i.e. truncation (instead of the standard mode 0 that rounds to even).
The round mode is set by the RM command which is part of the MODE menu.

Round to 12 significant digits. This is accomplished by the RSD command that can be found in the X.FCN menu.

Yes. ;-)
So all in all it's a procedure like this:
Code:
RM 4 // set round mode to truncation
[SCI] 11 // always show 12 significant digits
17 [1/X] 5,88235294118 E-2 // 1/17 rounded 12-digit display precision
[ENTER] RSD 12 5,88235294117 E-2 // first 12 digits
[-] 6,47058823529 E-14
[ENTER] RSD 12 6,47058823529 E-14 // next 12 digits
[-] 4,11764705800 E-26 // last 10 digits
RM 0 // reset standard round mode
