Yes, Will. There are two variables. The descriptor definition found in
$UVHOME/gcidir/include/DATUM.h states:
struct Dstring
{ /* This are my comments. GI */
STRING str; /* This is the entire dynamic array. */
int lastfield; /* This is the last field accessed. */
uchar *lastfptr; /* This is a pointer into str.text */
/* where the last field field accessed */
/* begins. */
};
