The continue command will skip the rest of the current iteration of a loop and go to the next iteration.
If you enter:
S:=0; for (j:=1,j<=10;j++) { if (j==5) { continue; } S:=S+j; } |
then S will be 50, which is the sum of the integers from 1 to 10 except for 5, since the loop never gets to S:=S+j when j is equal to 5.
