Error/misprint in ClearWin+ Tutorial

I,m using Plato 4.10 Step 6 of Tutorial contains the text of INTEGER FUNCTION factoriser() thas fas the line: IF(n.GT.1)GOTO 1 No label '1' in function Sorry, may be it is an old finding.

Looks like the 1 should be a label for the DO k=2,n

Thank you, Paul. May be someone updating the ClearWin+ Tutorial will recall it.
