One way would be to assure that the path is set in your sswidl script.
If you do not have access to this, you could also set the path from within IDL:
SETENV,"PATH=/bin"
(replace /bin with the correct actual path (hint: use the output from PRINT,GETENV("PATH") when run under plain idl))
HTH,
Marc

you seemed to have hit the nail on the head. i had confused the IDL variable !PATH with the environment variable, getenv('path').
IDL> help, getenv('path')
returns a null string.
could you also tell me the right way to fix it?
Anand.

Is the path environment variable set?
Check with:
PRINT,GETENV("PATH")
