Hi, I'd like to know how to set path in IDL. For example, my idl program is
in some directory. In the program, some datafile will be input. If I donot
set whole path including the directory, there is a falt indicating that the
data file cannot be found in rsi\idl. I hope that all the file in the same
directory as idl program will not indict whole path. How to do that? thanks!

I use the following code to determine the location of a .sav file
(courtesy of a source within RSI):
HELP, CALLS = calls
thisroutine = (STRSPLIT(calls[0], ' ', /EXTRACT))[0]
source = ROUTINE_INFO(thisroutine, /SOURCE)
CASE STRUPCASE(!version.os_family) of
'WINDOWS' : dirsep = '\'
'UNIX' : dirsep = '/'
'MACOS' : dirsep = ':'
'VMS' : dirsep = ']'
ELSE : dirsep = ''
ENDCASE
path = STRMID(source.path, 0, STRPOS(source.path, dirsep, /REVERSE_SEARCH))

Thank you.
All the other files are in the same directory with sav file. How to get the
path? I try to use
path=FILEPATH('test.pro'), to get the full path,
but failed. Are there any some function to do this?
