Hi
I am new to idl..I have been trying to fit the function poly_fit to my data but each time an error message comes:
% Variable is undefined: POLY_FIT.
% Execution halted at: $MAIN$
Its a lib defined function...

Suppose IDL is installed here:
/usr/local/exelis/idl82
And the lib directory is:
/usr/local/exelis/idl82/lib
Then, you could do something like this:
export IDL_PATH='+/usr/local/exelis/idl82/lib/'
export IDL_PATH=$IDL_PATH:'~/coyote/:+~/idlastrosoftware/'
You can add as many directories as you need, separated by colons. The
directories are searched in the order they are specified on your IDL
PATH (!PATH). So, for example, if you were going to add the Coyote
Library, you would add it before the Astronomy Library, since the
Astronomy Library depends on it.
Cheers,
David

You may print the variable !path. On my computer (Windows 7, IDL 7.0) I get:
IDL> print, !path
C:\Program Files (x86)\RSI\IDL70\lib\bridges;C:\Program Files
(x86)\RSI\IDL70\lib\dicomex;C:\Program Files
(x86)\RSI\IDL70\lib\hook;C:\Program Files (x86)\RSI\IDL70\lib\imsl;C:\Program
Files (x86)\RSI\IDL70\lib\itools\components;
[lots of entries removed]
To manage the variable !path you may open the IDL workbench and navigate to
window -> user settings -> IDL -> pathes
Maybe these steps have a slightly different name as I have a German version
of IDL. To repair setting you may click on "Restore standard settings".
If this doesn't help you may run the installer again to repair your
installation.

The issue is when i try compiling poly-fit it shows error opening the file.
IDL is not looking into its own lib. But it accesses another lib astrolib. So this I suppose is due to my path defenition. So if you would tell me how to define the path such that IDL looks into both libraries.
