How to convert curthread- t_sysnum to syscall name

Question

Hi,
I'd like to convert (kthread_t *)->t_sysnum to syscall name, can I search/walk through sb_hashtab or any other list in Dtrace?
I.e.:
*sb_hashtab::list struct bind b_next b_name|::print -atd struct bind{    300000e0180 struct bind *b_next = 0x300000e03c0
300000e0188 char *b_name = 0x30000100008 "lwp_mutex_init"
300000e0190 char *b_bind_name = 0
300000e0198 int b_num = 0t252
300000e03c0 struct bind *b_next = 0x300000e0900
300000e03c8 char *b_name = 0x300000ee888 "accept"
300000e03d0 char *b_bind_name = 0
300000e03d8 int b_num = 0t234
<snip>
Or, if I save the contents of /etc/name_to_sysnum in a ksh's array prior to calling dtrace(1m), I see that "scalar" shell variables are accessible via single quotes, i.e. '$var', but how can I access array syscalls[] using (kthread_t *)->t_sysnum as a index?
I.e.:
#!/usr/bin/ksh
OIFS=$IFS
IFS="
for line in `cat /etc/name_to_sysnum`
do
sysnum=`echo $line|awk '{print $2}'`
sysnam=`echo $line|awk '{print $1}'`
syscalls[sysnum]=$sysnam
done
IFS=$OIFS
/usr/sbin/dtrace -Cs <( print -r '
sched:::on-cpu
/'$opt_cpu'/
this->nlwp = curthread->t_procp->p_lwpcnt;
this->syscall = curthread->t_sysnum;
@oncpucnt[execname, pid, this->nlwp, this->syscall] = count();
Thanks,
Rob
