as a trivial example of the less easy to optimise loops:-

#include 
int main( int argc, char *argv[])
{   auto int n,count;
    for(count = 0; count < argc; count++)
        for(n = 0; n < strlen(argv[count]); n++)
            putc(argv[count][n],stdout);
    return 0;
}

    Here strlen() changes intentionally each iteration. The code is also
pretty dreadful because printf(" %s\n",argv[count]) would work
and look better.

    I guess it's a loophole, Neil. :-)

Best Wishes,
Bill.
