 DESCRIPTION
 This program calculates the value of a call and put using the Black and
 Scholes method.
 You can invoke it with just basop, it will ask you for the data.
 Or you can invoke it from the command line like for example:
 basop 92.00 95.00 .0712 oct 1999 .35
 where:
 92.00 is the current stock price
 95.00 is the option strike price,
 oct is the expiration month, only the first 3 characters of the month are
 compared, upper and lower case is treated the same, and Dutch  and  English
 language is supported.
 1999 is the expiration year, it MUST be 4 digits (or more....).
 You could use the C routines provided from within an other program.
 See text in basop for references and thanks.
 basop stands for Black And Scholes Option Program.
