Exploring Loops

Starset has an elaborated system of loop statements, including simple, sequential, and parallel loops.

A simple loop is a familiar WHILE loop that executes its body—a compound DO-END statement—as long as the loop condition is true. Consider a code fragment that implements a procedure for calculating the first count prime numbers. This example illustrates not only simple loops but also other important concepts:

1. The procedure is defined with the keywords PROC and ENDPROC. If it’s the first procedure in the program, it’ll be considered the main procedure and executed (see the example).

2. The procedure begins with variable declarations. You must declare every variable in a subroutine according to its type, which might ...
