File is the entire program.. like a global var?
Block is the "if" or "while" or other {} framed code?
what is an eval?
if (my $var=0;$var>10;$var++)
is that when you mean? an evaluation?

from what you say "our" is used in the main program
so I don't have to declare them again in the mod?
So if I run the mod as one big ad-in program to main
and not calling subs in the mod, I don't have to pass vars in the ()'s?
stats;
and not
stats::sub($var1, $var2, etc....);
this mode only does some calulations and print to the HTML code...
thanks
