So what you're after is the maximum size of
a scalar variable?
(what other languages would call a string, although
perl's scalars also handle numeric data)
Scalars (like all perl datatypes) expand
and contract dynamically
to fit the amount of data you try to stick
in them. I have used
large scalars before with no problems.
I just ran some quick tests on my system and stuck a 10MB
chunk
of data into a scalar and perl didn't even break a sweat.
