In ANSI C:

#include <stdio.h>
#include <string.h>
#include <ctype.h>

char text[]="Suppose some fellow (probably a reckless fool) wanted to
read an introductory book on Forth, what would you recommend?  He has
programmed in such languages as C, Modula-2, PL/M, ..., but not in
Forth.  Made weak by time and fate, but strong in will To strive, to
seek, to find, and not to yield.";

int main(void)
{
  int i=0;
  char *p=text,*a[256];

  while(p!=NULL){i++;p=strpbrk(p," ,.()?");if(p!=NULL){*p='\0';p++;a[i]=p;}};
  p=a[20];*p=toupper(*p);
  printf("%s %s %s %s %s.\n",a[20],a[58],a[66],a[45],a[49]);

return(0);
}

Output:

You will find Forth weak.

If the best that Ruby can do is to shave a few setup lines from C, it
really doesn't seem to me to be all that amazing.  Note that this is
ANSI C or C89 which was standardized in 1989, and not ISO C99.

I'd really like to see a Forth version.  I'm a bit unsure as to how
string processing such as this is handled in Forth.
