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:

$$ MODE TUSCRIPT
line=""
LOOP n=1,10
 line=CONCAT (line,n)
 IF (n!=10) line=CONCAT (line,", ")
ENDLOOP
PRINT line
