Some Test Needed

[frktons]

This is an experiment on the fastest way to convert a byte string
into a word string, that is double size of original one.

It is in the New Testbed [work in progress].

Could you please test it on your machines and post the partial screen displayed
as the following:

90 columns, 34 rows. The executable is set to work that way. If you assemble/link
the source you have probably to change console properties.

if i open the exe by clicking on it, it runs ok, but i cannot copy/paste the results with XP while it is running
the mouse is disabled while waiting for the keypress

so, i open a console window and type in the program name at the prompt
then, i exit the program to copy/paste

I don't remember how XP manages the console, but in Win/7 when I run the prog,
after it has displayed the test results, if I right click on the topleft icon I can have access
to the console properties, and see if the edit mode is selected or not. It should be.
This permits to select part of the screen with the mouse, or you can select all, copy
and eliminate redundant lines after pasting it somewhere.

Of course you should not be in full screen mode in XP.  :P

[dedndave]

ok Frank - that works
i can right-click on the title bar and access the edit context while it is running   :P

Good to know that XP has this capacity as well.  :U

What do you think of the overall project New Testbed?
Do you think somebody will ever use it?  :lol

Frank

[dedndave]

i do
however.....
i am thinking we may want a GUI app, though
not just because of presentation and appearance
it is more likely to provide a real-world environment for the test code to run under

you probably already have that on your to-do list   :bg

Well, I'm developing this version to learn some new ASM and to have a tool
to test the algos. Because the testbed used so far is just nothing more than
a sequence of algos and prints, I had the idea to build this new one as
an alternative as well with a more user friendly interface and some extra-bonus added.

The gui version could be useful as well, but algos are just that, and usually
a console mode suffices.

It'll suffice for a couple of years, at least for me.  :P

There are a lot of routines inside the New Testbed, and most of them are not
optimized at all. Experimenting with them, optimizing them will be my hobby
for the months to come. The program is not finished yet.  Testing all the PROCs within
with the same program will be its way of evolving  :lol

Yes, that's the same thing, but unicode could have a different second byte other than zero
if they are representing specific languages [chinese, japanese, and so on...]

Converting a byte to a word always means to put a zero in the high byte.
That's the difference.  :U

How did you get this unaligned display?

Frank

[ToutEnMasm]

How did you get this unaligned display?

I have just made a copy from dos.Think you haven't the same resolution than mine (800*600).
If it is that, you can try to use % for the dimension of your windows.

Two things:

1] use code instead of quote
2] select the area starting from the border and up tol the opposite border.

And after you can try to post again the results, maybe they will be more
readable.

I changed quote with code and it looks a bit better.  :bg
