#145 Cache' default disables Global Kills

[Dan Williams]

There are sever places in the VES* routines where a temporary global is KILL'd. By default, Cache's disables global kills so any attempted Kill results in an exception.

Either
set config variable GlobalKillEnabled to 1
or
the Kills could be wrapped with $ZU(68,28,0) \ $ZU(68,28,1)

Turn on unsubscripted global kills for just this Cache session:

s x=$ZU(68,28,0)

Turn off unsubscripted global kills for just this Cache session:

s x=$ZU(68,28,1)

Turn on unsubscripted global kills for all Cache sessions:

s x=$ZU(69,28,0)

Turn off unsubscripted global kills for all Cache sessions:

s x=$ZU(69,28,1)
