1. This agent uses an @For loop. The first parameter initializes the variable n to 1 and executes once. The second parameter tests whether n is less than or equal to the number of elements in Categories. The third parameter increments n. The fourth parameter is a statement that executes as long as the test remains True.

For(n := 1;
n <= @Elements(Categories);
n := n + 1;
@Prompt([Ok]; "Category " + @Text(n); Categories[n]))

n := 1;
@While(n <= @Elements(Categories);
@Prompt([Ok]; "Category " + @Text(n); Categories[n]);
n := n + 1)

@If(@Elements(Categories) = 0; @Return(0); "");
n := 1;
@DoWhile(
@Prompt([Ok]; "Category " + @Text(n); Categories[n]);
n := n + 1;
n <= @Elements(Categories))
