No, not really, but remember that you are free to do whatever suits you=20=

on the adapter side:-)

Sounds like encoding problems...

Just add a another function to the f2aqt file:

We already have:

int f2aqt_put_text__(int *x, int *y, const char *str)
{
   if (!strlen(str))
     return;
   [gnuTermAccess putText:str at:NSMakePoint(*x, *y)];
}

so I'd suggest something like:

int f2aqt_put_float__(int *x, int *y, float *number)
{
   /* This is a bit awkward, since we do number --> string object -->=20
char *
    	and then back to string object in the gnuTermAccess object...
	If anything, this tells us that the f2aqt was a quick hack, that=20=

needs improvement!
	NB. replace %f with whatever format you require
   */
   [gnuTermAccess putText:[[NSString stringWithFormat:@"%f", *number]=20
lossyCString] at:NSMakePoint(*x, *y)];
}

(written from the top of my head, never tested;-)

Now that's easy! Use the method - setFigure:

Add a function like this to f2aqt:

int f2aqt_set_figure__(int *fig)
{
   [gnuTermAccess setFigure:*fig];=09
}

and just calling it with any number n >=3D 0 will open Figure n for=20
drawing (but not shown until you call render...).

Don't forget to add their prototypes at the beginning of the file, just=20=

follow the general structure of f2aqt and you'll be OK!

There are some new documentation on http://aquaterm.sourceforge.net/ on=20=

how to write adapters.

FYI, I'll be releasing a 0.3.0 version of AquaTerm within a couple of=20
weeks (months?) and after that I'll turn to looking at adding/improving=20=

adapters. If there are features that you'd like to see in a fortran=20
adapter, pleas let me know. The preferred way would be via the feature=20=

request link on http://aquaterm.sourceforge.net/ or the aquaterm=20
developer mail list (that way everything gets logged, and more likely to=20=

be considered;-)

HTH,
