Number of digits written in exponents

6.9.3.4.1 ExpDigits is an implementation-defined value representing the number of digit-characters written in an exponent.

The value of ExpDigits is three (3) for the Windows edition of Irie Pascal, and two (2) for the other editions. So for example

   write('one=', 1.0)

will write

   one= 1.0E+000

   one= 1.0E+00

depending on the edition of Irie Pascal being used.
