Description:
This is my very first program in PILOT. I define a couple of string variables (starting with $),
I also use their values to define other string variables.
Then I output strings $A-$I (upper part of the snowflake),
output a line with all asterisks, 
nd output strings $I-$A (reverse order, bottom part of teh asterisk).

Comments:
Thanks for this great competition that forced me to use an already forgotten language PILOT!
