Error Compiling Program (2018-04-03 02:48 by toml12953 #81022)
Tis program works in Decimal BASIC but gives an error when trying to compile it
DECLARE EXTERNAL FUNCTION F
INPUT PROMPT "Enter semimajor axis a: ":a
INPUT PROMPT "Enter semiminor axis b: ":b
INPUT PROMPT "Enter Theta0: ":theta0
INPUT PROMPT "Enter Theta1: ":theta1
LET S = F(a,b,Theta1) - F(a,b,Theta0)
PRINT "Area =";S
END
EXTERNAL FUNCTION F(a,b,t)
LET F = a*b/2*(t-ATN((b-a)*SIN(2*t)/(b+a+(b-a)*COS(2*t))))
END FUNCTION
The error is:

The problem seems to be with the apostrophe in the file name (Area Using Kepler's Second Law) When I removed it, the program compiled OK.
