The fortran examples require the PGPLOT graphics library.

The CNF example requires PGPLOT and the CNF library to be
available on your system. Copies of the routines are
provided with and without the CNF code.

A Test script is provided for each. An additional function
interface has been implemented (PGQCR) to ease the testing.

Errata:

There is a typo on page 219 in the pgqinf definition.

  value[length+1] = '\0';

should read

  value[length] = '\0';

because the C string index starts counting at 0.

---

The pgscr XS interface on page 218 uses int for
cr, cg and cb when in fact they should be floats (as 
shown in the API description at the top of page 218)
