Hi Craig,
I've never worked with DLMs, so I can't say if they are also found
in IDL's normal !PATH. If so, you could use a somewhat more elaborate
startup file which would set the !PATH according to the !VERSION
variable. Please find attached my startup file which collects some
user information etc. then sets up a search path including (1) the
individual user's routines, (2) institute wide libraries, (3) IDL's
library.
The second solution if you are only dealing with different Unix
flavors (e.g. SOlaris and Linux), is to use uname in your .cshrc or
whatever shell you use. Example:
if ( `uname` == 'SunOS' ) then
# echo Sun Workstation
...
# IDL settings
setenv LM_LICENSE_FILE /usr/local/rsi/license/license.dat
source /usr/local/bin/idl_setup
setenv IDL_STARTUP ~/IDL/idl_startup.pro
...
endif
if ( `uname` == 'Linux' ) then
...
endif
Cheers,
Martin

; Preferences file for IDL
; Platform independent version, Martin Schultz 11 March 2001
; (may not work on all platforms yet)
; 1. Set filepath delimiter according to platform
dl = '/' ; Assume Unix as default
IF !VERSION.OS_FAMILY EQ 'Windows' THEN dl = '\'
IF !VERSION.OS_FAMILY EQ 'Mac' THEN dl = ':'
; 2. The IDL main directory (don't change)
idlexedir = !DIR + dl
; 3. Set default directory for MPI library
idlmpilib='~m218003/home/IDL/lib/' ; Assume Unix as default
IF !VERSION.OS_FAMILY EQ 'Windows' THEN idlmpilib=''
IF !VERSION.OS_FAMILY EQ 'Mac' THEN idlmpilib=''
; 4. Get user name, login ID and home directory
; (name can be overwritten in users .idlrc file)
name = 'nobody'
cmd='finger $USER | head -1 | cut -d ":" -f 3'
IF !Version.OS_Family EQ 'unix' THEN spawn, cmd, r
IF N_Elements(r) GT 0 THEN name=StrTrim(r,2)
user = strtrim(getenv("USER"),2)
homedir = strtrim(getenv("HOME"),2)
; 4. Set defaults for other user settings
initials = '..' ; The user initials
email = 'nobody@dkrz.de' ; The user email address
idlusrdir = homedir + dl + 'IDL' + dl ; The user IDL home directory
idlusrlib = idlusrdir + 'lib' + dl ; The IDL user's personal library directory
USE_OBSOLETE = 0 ; Use obsolete system library routines
QUIET = 0 ; Don't display settings
!PATH = ''
; 5. Define system variable with user information
defsysv, '!USER', { NAME:name, $
INITIALS:initials, $
USERID:user, $
EMAIL:email, $
HOMEDIR:homedir, $
IDLUSRDIR:idlusrdir, $
IDLUSRLIB:idlusrlib, $
IDLMPILIB:idlmpilib }
; 6. Try to locate user's .idlrc file and execute it. If not there, issue warning
usrfile = ( Findfile(homedir+dl+'.idlrc') )[0]
IF usrfile EQ '' THEN print,'%% No .idlrc file found in '+homedir
IF usrfile EQ '' THEN print,'%% Some settings in !USER may not be correct'
cd, current=curdir
cd, homedir
@.idlrc
cd, curdir
QUIET = Keyword_Set(QUIET)
; 7. Build IDL search path
; Normally, users will have defined their own directories in .idlrc so we
; have to append the common libraries to the !PATH variable
; 7.1 remember user path settings for status report
UPATH = !PATH
; 7.2 MPIfM wide libraries
XPATH = $
!USER.IDLMPILIB +'martin_schultz:' + $
!USER.IDLMPILIB +'mgs_objects:' + $
!USER.IDLMPILIB +'david_fanning:' + $
!USER.IDLMPILIB +'mark_hadfield:' + $
!USER.IDLMPILIB +'esrg:' + $
!USER.IDLMPILIB +'liam_gumley:' + $
!USER.IDLMPILIB +'jhuapls1r:' + $
!USER.IDLMPILIB +'craig_markwardt:' + $
!USER.IDLMPILIB +'tex2idl:'
; Other procedures, no longer in PATH
; idlusrdir +'objects:' + $
; idlusrdir +'hiphop:' + $
; idlusrdir +'gamap:'
; idlusrdir +'grib:' + $
; idlusrdir +'grib/gribidl:' + $
; 7.3 Build path for system routines manually to prevent obsolete coming before lib
; Omit all example files
SPATH = idlexedir + 'lib:' + $
idlexedir + 'lib/hook:' + $
idlexedir + 'lib/utilities:' + $
idlexedir + 'lib/macros:' ; this is only needed for IDLDE!
IF Keyword_Set(USE_OBSOLETE) THEN SPATH = SPATH + idlexedir + 'lib/obsolete:'
; 7.4 Compose !PATH system variable
!PATH = !PATH + XPATH + SPATH
; 8. Report status
print,'Welcome '+!USER.NAME
print
IF NOT QUIET THEN print,'The following personal libraries are included in the search path:'
IF NOT QUIET THEN print,UPATH
IF NOT QUIET THEN print,'The following MPI wide libraries are included in the search path:'
IF NOT QUIET THEN print,XPATH
; 9. Delete local variables
DELVAR, name, initials, user, email, homedir
DELVAR, idlusrdir, idlusrlib, idlmpilib, idlexedir, spath, upath, xpath
DELVAR, curdir, dl, r, use_obsolete
; 10. Increase length of input buffer
!EDIT_INPUT=50
; 11. Call Liam Gumley's COLORSET routine to ensure
; working colors
COLORSET,decomposed=0, quiet=QUIET
; 12. Goodbye
IF NOT QUIET THEN print,'Startupfile for user ',!USER.USERID,' processed.'
