How about this one:

How does one expand !PATH in a platform independent
manner?

CD, CURRENT = currentDir
!PATH = EXPAND_PATH ('+' + currentDir) + delimiter + !PATH

"delimiter" is platform-dependent, but required :-(

You can use the system variable !VERSION:

case ( strupcase(!version.os_family)) of
'UNIX': delim = '/'
'MACOS': delim =
'VMS': delim =
'WINDOWS': delim = '\'
else: print, 'OS uncrecognized'
endcase

!VERSION.OS contains more specific OS information.
