The above example shows that ONTICK continues to run after a CLEAR statement but variables are cleared.
If a program error were generated after the clear, the program would stop because ONERR was cleared.
The next example demonstrates how CLEAR S can be used in a FOR-NEXT loop. A C-STACK error is
returned if the CLEAR S is not in line 20.
10 FOR N=0 TO 10
20 IF N=5 THEN CLEAR S : GOTO 10
30 PRINT N
40 NEXT
