Everybody can write such a subroutine, when really needed. Or use what 
the RTL provides for such purpose...

I think that you are abusing strings for demonstration purposes only. I

mistake while counting characters, or that you missed to organize your 
super-long string into smaller pieces (lines, columns...).
