[m-users.] Question about strings

[Astrid Garcia]

One part of my project consists on taking as input a number and a string
from the user. Process the number and mod it with 5 and the result will be
the times I will duplicate the string that they input. I got the math part
correct, but I run into problems when I try to read and store the string
and to duplicate it. I am confused as to what is the equivalent on Mercury
of the Java  while loop, the "if (x == 1)" expression and the reading from
user like the "string = input.nextLine();" in Java

Thank you for your help and time,

Astrid Garcia
