Re^2: Use of do() to run lots of perl scripts

do is just a glorified eval `cat FILE` mechanism.

... without creating a sub-process and running cat, of course.

of course that's why I said "mechanism" and linked to the `do`cs. `do "./stat.pl" is largely like` eval `cat stat.pl`; `except that it's more concise, runs no external processes, and keeps track of the current filename for error messages. It also differs in that code evaluated with do FILE cannot see lexicals in the enclosing scope; eval STRING does.` Cheers Rolf _{(addicted to the Perl Programming Language :) Wikisyntax for the Monastery}	[reply] [d/l] [select]

do

do "./stat.pl" is largely like

eval `cat stat.pl`;

except that it's more concise, runs no external processes, and keeps track of the current filename for error messages. It also differs in that code evaluated with do FILE cannot see lexicals in the enclosing scope; eval STRING does.
