50g

> Tim Ed here. Just wanted to say thanks for the help I received

from your program. You have no idea the struggle to store data out on
the 49G's SD card using the information in print for the 49G. There
is a brief note about using the :3: to reach the SD memory.

Well thanks. Glad to help.

The SD card training document on HP's site is pretty good. Its the
second or third one.

> I have a couple of questions; is it possible to determine how

many objects are stored on the SD card?

Use a PC program. You can't with built in tools get back a list of
directory contents on the SD card. However, CdB (hp's engineer in
Boise) once wrote for me a small routine that brings backa list of
directory names. It is buried somewhere in comp.sys.hp48.
Unfortunately long names weren't supported.

> and is it possible to simulate a key stroke in a program?

Yes. The KEYEVAL command is designed for that. To use it, count the
rows down, then the column over, then add a decimal, then add the
shift state (.1 is regular click, .2 is either R or L shift, etc)

So to click the down arrow and edit something in level 1, 35.1
KEYEVAL would do it. To hit ENTER, type 105.1 KEYEVAL and so on.


( I know that ON and F6 pressed together will bring up a menu and that
preesing 8 will give battery condition and a hex value for the voltage
but how to use this.) Any help will be really appreciated. Thanks
again. Ed Von Essen

The only way to get that info outside that menu is to use some
assembly to pull the value back. There have been quite a few
discussions regarding the hex value on comp.sys.hp48 Here is an
example of one:

There are several programs here designed to get the battery voltage
and display it. Not sure if all of them work still though.
