variable set and call

#!/bin/zsh

#First I'm going to set variables that will in the end be the answers to this simple program I'm writing:

#Variables

MOM=SHERRY
SON1=LANCE
SON2=CHAD
FATHER=RICKY
DATE=$(date)
ILU="I love you mom and I'm sorry for allI've put you through, I hope you know you will always be the best woman in the world. There will never ever be a better mom. Thanks for all you have always done! we all love you !!" 
 

echo " Hello, my mother is $MOM and my father is $FATHER ";
echo "They had two sons, $SON1 and  $SON2";
echo "Once variables are SET with a value then they are called in a command with a $ which indicates you are summonsing the value of the variable listed after the $.   echo is a command that just prints the characters in the line with the variable results to the screen."; 
echo " My simple variable example program is all finished now. I finished this program on $DATE  Thank you and I hope you learned a little from my simple program I wrote to help you understand variables and commands."; 
echo $ILU;
echo " I hope you learned a little something I am going to run the program and show you the output after you see this the source code";
exit
