NAME: spd_ui_req_spin PURPOSE: Determines availability of parameters for spin model. CALLING SEQUENCE: if spd_ui_req_spin((coordSys,value,probe,trange,loadedData) then begin thm_load_state,probe=probe,trange=trange,/get_support endif INPUT: value: a string storing the destination coordinate system active: the set of variables to be transformed loadedData: the loadedData object sobj: the status bar object to which messages should be sent silent(optional): set this keyword to suppress popup messages.(Used during replay) OUTPUT: none SIDE EFFECT: New active variable for each prior active stored in loaded data and transformed into the new coordinate system with suffix added/changed HISTORY: $LastChangedBy: egrimes $ $LastChangedDate: 2014-02-21 13:54:28 -0800 (Fri, 21 Feb 2014) $ $LastChangedRevision: 14413 $ $URL: svn+ssh://thmsvn@ambrosia.ssl.berkeley.edu/repos/spdsoft/trunk/spedas/gui/utilities/spd_ui_req_spin.pro $
