note that in some cases, this method is not safe. This because some PVs 
allocate structures in memory for the name. $var is safe, as a first 
look, but $sht isn't it. For AVP you have a special perl class and 
should be the way to access unsafe PVs - copy it to avp before calling 
the perl script.

Cheers,
Daniel
