The values followed by a + character in the translation table indicate an error.

EXAMPLE

#include "mut.h"
#include "mlo.h"
lofig_list ∗ getgoodlofig(figname, mode)
char ∗figname;
char mode;
{
lofig_list ∗ptfig;
	ptfig = getlofig(figname, mode);
	restorealldir(ptfig);
	guessextdir(ptfig);
	return ptfig;
