could be done in several ways
* if it is compiled, help,/source,out=out
* look for "current directory" or "get_profile_path" in the google forum or
http://www.fz-juelich.de/icg/icg-i/idl_icglib/idl_source/idl _html/dbase/get_profile_path_dbase.pro.html
* file_which if the routine is in !PATH

you should think on using a startup script which organises the !path for
you. A startup file is used in idlde and idl the same way. just only an
environement variable IDL_STARTUP must be set to this file.

Then you want to separate between path file and extension.
you should have a look at:
