Setup instructions:

----------------------------------------------------------------------------------
You can download the latest version of FORWARD codes at

	 web directory  containing two tar files:

	forward_[date].tar has the  programs
	forwarddocs_[date].tar has the documentation and examples

You do an update by completely deleting old versions - e.g.,

	 rm -R FORWARD 

and expanding a new tar.

Since it is still in beta-testing, forward_[date].tar is likely to be updated more frequently than the documentation/examples.
----------------------------------------------------------------------------------
----------------------------------------------------------------------------------
The forward code uses IDL and the Solar Soft tree.

 Solar soft tree installation instructions


Make sure to get the following packages - in your initial setup and then in your solarsoft preferences (e.g., in your .cshrc):

	setenv SSW_INSTR "binaries chianti eis xrt eit trace secchi aia pfss"
----------------------------------------------------------------------------------

----------------------------------------------------------------------------------
The CoMP related codes also use fortran routines requiring a fortran compiler. 
The FORWARD tar file will have a compiled version of the main code, forcomp, that
ports pretty easily to Mac Os X machines. There is some information on installing 
and compiling fortran codes for other machines in 

	FORWARD README
----------------------------------------------------------------------------------


----------------------------------------------------------------------------------
Once you have unpacked the code define a logical, FORWARD, pointing to the directory

For instance in unix:

	setenv FORWARD '~myusername/whereveritis/FORWARD'

Make sure that the FORWARD directory is in your IDL path. One way to do
that is to type the following at the start of the SSWIDL session

	 IDL> add_path,'$FORWARD',/ex

Alternatively, you can take care of both with the following lines in .cshrc in unix:

	 setenv FORWARD ~myusername/whereveritis/FORWARD/
  	setenv FORWARD_DOCS ~myusername/whereveritis/FORWARD_DOCS/
  	setenv IDL_PATH +${IDL_DIR}/lib:\+$FORWARD/:\+$FORWARD_DOCS/

this way you can run examples from other directories.

If you don't have IDL_DIR set (check by typing printenv IDL_DIR) you can
set in your .cshrc by 

	setenv IDL_DIR  directory_where_idl_lives
----------------------------------------------------------------------------------

----------------------------------------------------------------------------------
You run the FORWARD codes either from command line  (see Examples).

Or you can now use the widget interface:

	 IDL>for_widget
----------------------------------------------------------------------------------

----------------------------------------------------------------------------------
There is more material describing the FORWARD tree in
	FORWARD README

This includes information about setting up FORTRAN, and an overview of the codes...
