Dear Olaf,
IDL searches routines along its search path but it looks first
in the path were idl is in.
cd,current=current
print,current
You can define this path by idlde preferences path or startup.
We prefer the startup method.
Because it is necessary if you have a library and many users
all of them should have the same order of pathes.
You can define a function like
function my_func
struct={a:1}
return,struct
end
If this is saved in the search path it is loaded
by x=my_funct()
If you like named structure you can define them in the startup file
too.
Then you only have to call them by x={name of structure}
regards
Reimar
