Hi, everyone,
Dose _EXTRA pass the keywords from the caller to called routine or the
opposite?

You may be also interested into the _REF_EXTRA keyword.

The presence of a name in the _REF_EXTRA value indicates that a keyword
of that name was passed, and its value is available to be passed on in a
function or procedure call (using either _EXTRA or _STRICT_EXTRA).

Hi everybody,

I tried to use the _extra keyword to pass some values through the lsode function to the function 'myfunc' called by lsode to avoid common blocks but somehow lsode does not pass the _extra variable.

Does lsode accept the _extra keyword? I didn´t find it in the help description of lsode.

Cheers,

Heiner

I think a common block might be your friend, in this case. :-)

Cheers,
