the character up vector.
.SH SYNOPSIS
CALL GQCHUP (ERRIND, CHUX, CHUY)
.SH C-BINDING SYNOPSIS
#include <ncarg/gks.h>
.sp
void ginq_char_up_vec(Gint *err_ind, Gvec *char_up_vec);
.SH DESCRIPTION
.IP ERRIND 12
(Integer, Output) - If the inquired values cannot be returned correctly,
a non-zero error indicator is returned in ERRIND, otherwise a zero is returned.
