Yes,

I think you can use fstat or spawn,'ls',result to detect if the file is
new.
If it is new you can use:

resolve_routine,'plscript' =

a =3D execute('plscript') =

resolve_routine will compile the procedure plscript and the following
function will execute it.

plscript will be the routine which reads the data and will produce the
plot.
