I continue to be impressed with the power that I can hold in my hand
with the Pocket PC and J on it. I have finally played with it and took a
simple script from my regular PC and tried it on the Pocket PC.
Following is the script boiled down along with comments on some
differences I found.

Random comments:
I assume that the goal of the Pocket PC version of J is to be as nearly
compatible with the bigger versions as is practical. That seems to be
quite good for internals and for graphics so far. However, the basic wd
commands seem to have a lot of differences. Generally, I feel that valid
wd commands for regular PC J should not cause errors on the Pocket PC,
but should be ignored if not supported. What I mean is that such wd
commands should not cause a domain error. But it would be nice if a list
of commands which are not intended to be supported be available.
Running the above script on my PC with Windows XP and then the same
script on my XP 6700 gave the following differences:
0. Edit objects have no border. They are invisible on the form but I can
tab to them and type in them.
1. Specifying ws_thickframe give a vertical bar on the left of the edit
object.
2. es_right ignored.
3. setcolor not supported, causes wd domain error.
4. qprinters not supported, causes wd domain error.
5. Buttons don't change appearance when the current object on the form.
6. Overlapping objects have different one on top.
7. At one time got an error which showed up in qer as "command not
supported : 1085". What is 1085?
8. If there was an error on my form then I couldn't get Menu J/Next or
J/Previous to work. I had to rerun j.exe to get them to work. Also,
typing into the ijx window wouldn't work either - The cursor was gone in
the ijx window. Also, sometimes the ijx menu list disappears (except for
the J) when a wd error occurs.
Other comments:
9. I can't figure out how to tell if I am running on a Pocket PC or a
regular PC on WINCE. wd 'wm' and wd 'qscreen' give accurate screen sizes
but that doesn't seem like a good way to tell.
10. One thing I am doing is putting a lot of stuff onto a storage card
and on LAN. I can't figure out how to get those folders to show up for
the file menu. I can access them with the normal J file conjunction and
also can access them through USERFOLDERS. One thing I tried to do was
create a shortcut, but I can't find a way to create a shortcut like I
can on Windows XP. I can create files of type ".lnk" but they show up as
normal files if I specify "all files" and just open the file as a script
if I select it.
