Maybe. I'll try.

You're right, went back and checked code (I use broadband and access
this group on a machine different than my development machines).
String was non-null.
But, getvaraddr returning NULL for a NULL string is very bad news.
It means getvaraddr isn't a good test of whether a variable has been
declared, so this will cause plugin xxx to throw an incorrect error:
local myVar
local result = xxx.serv("myVar")
assuming xxx.serv expects name of a declared var as argument.

No great urgency. When you could get to it, maybe GetVarSize(argname)
can return -1 if no such variable has been declared. Meanwhile
I'll issue dll plugin with workarounds and a bit less safety for
func calls that use BYTE* arguments.
