    So i've been set this task as part of revision and have no idea how to go about finishing it:

    Write a program to accept three (INTEGER) lengths and report back on whether these
    lengths could define an equilateral, isosceles or scalene triangle with 3, 2 or 0 equal length
    sides, or whether they cannot form a triangle.

    Hint: If three lengths form a triangle then 2 times the longest side must be less than the sum
    of all three sides. In Fortran terms, the following must be true for a valid triangle:
    (2*MAX( side1 , side2 , side3 ) < side1 + side2 + side3 ).

    I have attached what i have done so far as an image.

    any help is hugely hugely appreciated!

    thank you

    So what's the problem? You don't know fortran or you don't know understand what you want your code to do?

    Ps. posting pictures of code listings angers the dragons.
