Hi everyone,
My SAV file use 'call_function' command.
The 'function_name.pro' which called by 'call_function' command is to
load image, but every experiment we will create new
'function_name.pro' for the new images,it is impossible to compile and
enclose all 'function_name.pro' in SAV file in advance.
Is it possible for SAV file to call external function which doesn't
enclose in SAV file?? Thank you very much!!
With best wishes,
Rongchang

I guess both David and Reimar are correct... VM does not allow to run
un-compiled code (otherwise nobody would be buying IDL anymore!!!).
However, you might have similarities in your images that you can
exploit. For example, if the only differences are only the size of the
header or the data type, you could have a GUI or a PROMPT that ask for
those info, and act, in your pre-compiled code, accordingly...

If you can share an example source of the function you enter
we can discuss how to solve this issue differently.

I think at this stage making *any* kind of assumption will
only result in increased newsgroup volume. I'm already up
at 4AM to deal with the onslaught, but I think in the end
the answer won't change. I'm 99 percent sure the answer
is "no". :-)
Cheers,
David

The question is how that on the fly created function looks like. If he
shares an example we can discuss how that issue could be solved.
I assume that most of the code used in that function is already compiled.

Not to my knowledge, no.

Thank you for discussion.
I would like the SAVE file which run on Virtual Machine works
following way:
1. One can enter the image open function name in the 'widget_text';
2. GUI get the function name and call the function to open images.
OK,if the function name is pre-compile then it work well,but if i need
to use new function name which doesn't pre-compile in SAVE file,then
it doesn't work.Because the function name is change time by time,it's
not convenient to recompile again,also not good for source code
protect in my opinion.
Can this problem be improve?Thank you!
Best wishes,
Rongchang

where is the example function you create on the fly?

Yes I want to run SAVE file on Virtual Machine.CALL_FUNCTION need pre-
compile all routines,can other commands or methods support to call idl
routines which doesn't pre-compile in SAVE file? Thank you!
