REVERSING A STRING:
------------------------------------
This program displays the user input
in reverse order. It uses user defined
function for that purpose.
The output shape prints the program heading.
The declare shape create a string variable.
The output shape prints the user prompt.
The input shape stores the entered text in mystring variable.
The output shape prints the result heading and reversed string.
This is done by calling user defined function.

Reverse Function:
----------------------------
Reverse (text) is user defined function,
with text variable as parameter.
The declare shape declares a string variable.
The assign shape stores all spaces in Rtext variable.
The Declare shape creates integer variable, i.
The For loop iterates throughout the length of string.
which is passed to the function.
The assign shape stores each character in the string,
in reverse order in the variable -Rtext.
This is done with the help of Char(string,integer) , built-in-function.
This function returns each character in a string as per the index of
character in the string.
Finally, Rtext is returned to the calling function- here main function.
