Sorry, I didn't see that thread. I'm still having trouble finding it, but here's a better looking version of the code:

Code:
typedef  enum {now=10,  next, last} grade;
typedef union {int age1 ;float age2;} age;

main()
{
  struct {char name[20]; int age;} info;
  grade now;
  strcpy(info.name, "my name is here in the real code");
  info.age=15;
  union age=info.age;
// parse error before 'union'
  
  printf("This program is by %s, age %d. He is currently is grade %d." IFNO.name, age.age2, grade); 
// parse error before 'info'
}
