>What is the sequence you use to call the PRGM menu to the top key roll? If I use 23 MENU [ENTER] and press [left-shift][IF] or [right-shift][IF} I get one of both IF-THEN-(ELSE)-END structures.
I'm using here [left-shift] PRG BRCH IF to get there (I'll try 23 MENU [ENTER] tonight). Then I encounter either of the following phenomenons:
1. [left-shift] [IF] returns IF THEN END ok. But subsequently pressing [left-shift] [IF] (e.g. in order to insert an IF THEN END after the 1st IF) stalls the machine.
2. [right-shift] [IF] returns IF THEN ELSE END but stalls the machine immediately.

It has just been curiosity if there's some sort of bug in OS 1.18 ...

Well, I've just started to use this HP49G which I bought 2nd hand. So, I can't tell what the previous owner did with it (except of loading 2 libs that I purged lately). Anyway, I'm currently enjoying the excellent Trigonometry-, ComplexNumbers- and SequencesSeriesLimits-Marathons of Nick (can't remind his complicated, long greek name)-- b.t.w., an absolutely incredible work that the guy did here. I have had some problems to follow the course due to missing commands with OS 1.18 and so I'm indeed planning to upgrade to 1.19-5 soon anyway. However, thank you very much for your help!
