Hi Aleksandrov
Thanks for the reply.

Yes my checks should be more specific.

On the side how , i'm facing difficulties to print script variables
and hashtable entries.

xdbg("my var [$var(temp)]")
xdbg("my hash entries [$sht(a=>$ci)"])

Both statements shows parse errors. What's the correct syntax to print script
variables and hash table entries?

"xlog" module documentation does not seems to address this.

Cheers.
