A problem conc. Dynamic compiling using linked functions from within O2

[RobbeK]

Hi all,

Seems I need to delete function declarations (linked to O2) from within TB to be able to reuse them.
Been browsing the help files, but for the moment I found nothing.
If it is not possible I can do it without the linked functions (by a simple O2_EXEC), but it should be handy ...


thanks in advance, Rob

Hi Rob,

The variable linkage of the first compile appears to carry over to the second compile.

But I found that inserting an empty compile before your second compile, fixes the problem:

o2_basic ""
o2_basic s

[RobbeK]

Ah, excellent !!

I was working on something to bypass the usual "Eval" by using O2.
But already converted it to a "global" 02 call in the mean time -- but i'll convert it back.

In the program the textbox at the bottom left accepts any formula (within the Oxy syntax ) - the compiling is done by pushing the O2 button.
Scaling of the z values (f(x,y)) is done by half values/double values (buttons). Scaling the grid x,y is auto etc... animations by the cursor keys ...

(can be handy for young math students , wanting to have a look ... a picture tells more than 1000 words (infact this are 10000 numbers representated :-)).


thanks Charles !

I'll be damned! :o

Hi Rob,

I think using shared variables and the simple o2_basic / o2_exec scheme, as you have done here, is the best solution for this kind of program.

I recommend removing the bye() procedure, so that Oxygen will automatically terminate, freeing all of its resources at the end of each o2_exec.

Thanks Charles , Mike ..

Charles,

Could you please provide me a link to something
that explains Oxygenbasic's interaction with thinBasic?
I mean like it's purpose for thinBasic and what it's
suppose to do for it.

Thanks,

Bill

Hi Bill,

I have revised the original thinBasic_Oxygen compiler module post, containing a brief description.

I hope this helps.

And I would be delighted if any of the innovations in Oxygen might also be usefully deployed in thinBasic itself.

Thanks for setting the trap. :) Once Eros accepts that PowerBASIC (and its author) is dead, maybe he can use ALL the features of O2 rather than piece mealing them in.
