I just looked at my well-read copies of both books and couldn't find this.
In "More Programming Pearls" Bently discusses PIC and gives a prototype
implementation of PIC, but he only mentions GRAP in passing. I think
that the AWK prototype for GRAP is in Aho, Weinberger and Kernighan's
book "The AWK Programming Language", but my copy is at work and I can't
check right now.
