Units in CAS mode? - Ollie - 05-16-2015 10:18 PM
Hey, I've tried learning how to use the prime unit system properly but failed miserably.
I checked the user guide .pdf and they had an example:

Well, I tried this with the emulator and here's what happened:

Uhh, that's a bit weird, how about in the normal non-cas mode:

Seems to work fine, but wait! This works in cas mode:

That's a bit odd, isn't it?
Alright, well next up unit conversion.
CAS:

Fails, how about the non-cas mode?

Doesn't make any sense.
MKSA?

NOPE, works fine in normal non-cas though.
Same with USIMPLIFY..
So, why can I not use units properly in cas mode?

There are a few differences in usage between Home and CAS units. Instead of "in" you must use "inch" (see http://www.hpmuseum.org/forum/thread-1611.html).
You get the correct result but the original command line is mangled in the results screen:
As for the CONVERT and MKSA examples, I have no problems.

Try doing that from Home View!

How can you get the conversion working? All the CAS spits out is "Error: Unmatch control word".

Well, it works well if you pick the MKSA from the Units>Tools menu, there seems to be a display bug if the MKSA command comes from the Toolbox Catalog:
This is only a display bug because if you select the result and copy it to the command with a double tap, it is the correct one:
On the physical Prime I get a different exponent: 112 instead of 69. I have the latest firmware rev. 7820.

Does not work for me on either prime or emualtor, even if I select it from the toolbox.

I've no clue why it is not working for you. Do you have the latest firmware version (7820)?
On a side note, you can do screen captures directly from the emulator or the connectivity kit.
