FoilCheck Change Log
                      --------------------

19-Jan-1994
 Added subroutine foilnew which will calculate a new airfoil from
 -180 to 180 using Viterna.

18-May-1994
 Major rewrite to use more subroutines, completely automate generation of
 airfoil file.

16-Aug-1995
 Updated for compatibility with multiple airfoil files (many array
 dimensions increased) (9.3)

10-Jun-1996
 Changed CN at stall (CNS) from table lookup to interpolated value from
 CN slope Also updated to include Beddoes changes in YawDyn between ver
 9.3 and 9.6 (9.6)

11-Dec-1996
 Added pitching moment table and extrapolation.  Also brought up-to-date
 with all changes in YawDyn 9.89

15-Dec-1996
 Changed angle of zero lift calc. to use curve fit results (9.90)

16-Jul-1006
 Overhaul of entire program to provide better prompts, and provide
 defaults to (Y/N) prompts.  Automated more calculations while still
 maintaining operator discretion.  Added check for existence of input
 file to avoid program abort.  Added CD column to list in Viterna
 Coeffecients routine.  Added pauses to screen output to avoid scrolling
 new text off the screen.  The program is now generally more user
 friendly. (11.0)

26-Mar-1998
 Added check for small CD in Viterna subroutine.  Minimum CD allowed in
 viterna calcs is 4* CDALMIN (from original table).  Borrowed subroutines
 CurTime and CurDate from YawDyn 11.0.  Changed output so only one
 airfoil table is output to foilnew.plt (to avoid mixing incomplete
 airfoil data tables with complete (-180 to 180) ones).

27-Nov-2001
 Updated the program to be compatible with version 12.0 of
 YawDyn/AeroDyn, written in free-form Fortran 90.

12-Mar-2001
 Updated program to remain compatible with version 12.10-beta.

04-Jun-2001
 Updated to work with release version 12.3 of AeroDyn

18-Jul-2001
 Fixed bug that prevented CM calculations when the table did not span
 alpha for zero lift.

v2.02 13-Nov-2001
 Fixed bug that crashed program if airfoil file has no return at the end.

v2.03 30-May-2002
 Updated FoilCheck to work with new AeroDyn subs and mods.  Increased size 
 of character variable Prog to avoid truncation.  Changed initial value of 
 ANSWER to activate default setting.  Changed dimensions of Int2LStr and 
 Flt2LStr to reflect correct values in new AeroDyn.  Somehow fixed a bug 
 found by M Hand of NREL.  Lucky me.  No changes made to code functionality.
