As far as I know, you need a seperate file for each
parameter. So you could have files such as:
GlobalFile_1.GalaxyParameter1 containing
2.56
GlobalFile_1.GalaxyParameter2 containing
1
etc.
Then, you would use the edit parameters window of
the galaxy the parameter values to
<GlobalFile_1.GalaxyParameter1
<GlobalFile_2.GalaxyParameter2
etc. Of course, you would have to use valid pathnames
in front of the filenames.
This probably doesn't help you for what you really want to do.
What I've done in the past when I want a lot of information from
one file is to set the filename as a star parameter then write some
C++ to parse the file. What you might also try is to create a
star with a parameter of string type, then set its value to
"<GlobalFile_1" I believe this will put the entire contents of the
file into the string, where you can parse it. I've never tried
this though (it might just read the first line of the file).
None of this helps setting galaxy parameters because it
only works within a star. When I run universes using ptcl, I have
an awk script that goes through and sets universe and galaxy
parameters beforehand. Not the prettiest thing in the world, but it
works.
Hope some of this is helpful.
