!Path re-parser anyone? [message #250]

I would like to be able to re-parse the !PATH system variable within
the context of IDL, in the exact manner which IDL uses to convert
the logical (or environment variable) IDL_PATH during startup, INCLUDING
the "+" notation and the removal of duplicate entries.

Example:
If (StrPos(!Path, 'MYLIBRARY') eq -1) then Begin
!Path = !Path + ',+my_home_directory' ; VMS notation here
PARSE_PATH [, !Path]
EndIf

I've lobbied RSI to add this function. Has anyone out there already written
one? We would find it very useful.

Thanks again,
