[En-Nut-Discussion] Need Help on Matrix prog_char

[Ralph Mason]

How about (not tested and likely to contain one or more bugs)

void gstring(FILE * stream,int line){
	PGM_P str = PSTR("Line1\0"
			 "Another Line\0"
			 "Yet a third\0"
                         "Forth line\0" );

	while(line--){
		while(PRG_RDB(str++));
	 }

	fputs_P(str,stream);
}

Cheers,
Ralph
