DB48X: HP48-like RPL implementation for DM42

Thanks again for release 0.8.7. I was using the CATALOG to look for Attach and Detach added in the release and it led to this question on the behaviour of CATALOG. I understand that CATALOG is context sensitive, which makes sense if it bring functions that are likley to be of immediate use to objects on the stack, say. That's great :-)

This post refers to DB50X v0.8.7 on my DM32.

What I am unsure about is the cyclic nature of CATALOG. I have assumed that if I cycle through the CATALOG menus using the forward and back soft keys (F6 and SHIFT F6) I will be able to get to all functions or menus eventually and that it is a big loop. Is that right?

Yes, although this is a very inefficient way to use the catalog.

The intent is that you start typing something, and then you cycle through what begins with or contains what you typed. So for example if you are looking for "background" functions, you type "BACK", and then you only have two pages worth of commands. If you type "AS" or "AX", there are only 18 commands, so it fits on the first page.

Quote:If I have nothing on the stack, I press f CAT (f = one press of blue function key on DM32) I get a set of 15 functions (F5 = %T) and the arrow keys of F6 and f F6. I can hit the F6 key (forward arrow) 42 times and am back at the first CATALOG menu (the one including %T on F5).

If I have a number (I type the number 3) and press forward ~44 times, I finish on a menu very similar to the first menu (with %T) but the F6 key has %Total, = and acosh. But there are no forward or back arrows on any of the soft menu keys. Is this intended?

No. Next time, can you please take a screenshot (holding Shift and DISP together, the snapshot is in the SCREENS directory)?

Quote:In my several attempts to reproduce this "dead end" or "cul-de-sac" menu, the number of times I press forward arrow (F6) seems to vary. Another test it took 98 presses of the F6 key. Perhaps I have misundertood something? Anyone else seen this or maybe can explain?

98 presses sounds closer to what you should get. My guess is that you pressed something on the command line that caused the catalog to shrink to the number of pages you observed.

Mark.
