index_page_pa

	status.i2.v = index_page_pa(page_name.i1a.r)

	This function will translate an ASCII index page name to
	a primary application (PA) number.  For example, "M004" or "M4" or
	"M  4" will return the value 52 because PA0052 is mapped to
	index page M4.  If no application is mapped, this function will
	return a 0.  A negative number indicates a user or network error.
	This routine uses the CLIB miscellaneous ACNET standard error
	code facility.

	page_name	ASCII index page name (PAGE_NAME_LEN characters)

	This function returns status values as follows:

	CLIB_IPP_BADCHAR	bad character passed  (The passed page
				number does not contain a valid index page and
				number character string.)
	CLIB_IPP_NETERR		network error  (The communication with
				Database to translate page number to PA failed.)
	otherwise		Primary Application (PA) number

	This function requires the following include files:

	clib_h, acnet_errors_h

	Related functions:

	pa_to_index_page_c

	C/C++ usage:

	static const char	page_name[PAGE_NAME_LEN+1] = "M4  ";
	short	status;

	status = index_page_pa(page_name);
