Well, that (half) explains that bit. Thanks.

Problem is, in the sample (pod) code,

• $CACHE is used, but never given any value.
• In this particular use of open, its not clear what value I would give the scalar variable of the same name?
• It appears as if, in the case of Inline::Files, that it is the name of the scalar variable of the same name as the filehandle that is being used - which seems (to me) to be a little redundant?

I freely admit to still being a newbie to this stuff, but to implicitly use the name of an undeclared, uninitialised global variable, with the same name as a supplied filehandle, to supply the name of the virtual file to open.....(phew)...seems...erm...a little confusing?
