Problem Statement

Quite often one needs loops which, in the last iteration, execute only part of the loop body. Demonstrate the best way to do this. Write a loop which writes the comma-separated list using separate output statements for the number and the comma from within the body of the loop.

Let's start with the solution:

DO i = 1, 10
    WRITE(APPend) i
    IF(i < 10) WRITE(APPend) ", "
ENDDO
