howdy!

you can append additional directory names to the !Path system variable
like so:

dir_name1 = '~/prog/idl'
dir_name2 = '~/arcsym/tools/idl'

!Path = dir_name1 + ':' + !Path
!Path = dir_name2 + ':' + !Path

the IDL documentation says though that !Path only works for .pro files, etc.

for data files, i generally prefer specifying a string variable that has
the entire path in it, and appending it to the filename, like:

pathname = '/users/johnny/datafile'
filename = 'foo.dat'
fullname = pathname + '/' + filename

maybe someone else has help on specifying paths for data files.

best,
-Johnny
