B.2 Running IDL (run_idl)

The file $ys/gen/setup/run_idl is a script which performs the Yohkoh IDL startup procedure. When working within the Yohkoh environment, this script is run when a user enters the command idl. The alias idl is defined during the execution of idl_setup.

The following functions are performed by the run_idl script:

• define the IDL SW !path (Concatenation of Yohkoh, Personal, and IDL paths)
• setup remote X display if not already set (selected systems)
• display message of the day
• execute the Yohkoh wide IDL_STARTUP
• optionally execute user defined IDL_STARTUP
• enter IDL

The following additional options are available by entering a second parameter on the command line:

% idl nox       # bypass X windows setup - useful to avoid color table
                # corruption caused by 2nd IDL session or to speed up remote

% idl tek       # startup with plot device set to 'TEK' (Tektronics mode)

% idl noys      # do not include Yohkoh paths in IDL !path setup 
                # for non-Yohkoh IDL work(?!)

% idl fast      # define path from file (faster) [if supported at site]

% idl ahead     # place personal path ($IDL_PATH)  ahead of Yohkoh paths
                # in IDL !path variable - default is Yohkoh paths first
