that is good.

that is wrong. don't call subs with & as it isn't needed and can cause a
bug if you don't know what you are doing with it.

don't do \" if you can help it. use other internal markers like [] or ''
instead. if you must have " inside a "" string, use an alternate delimiter.

well it does require being declared BEFORE it is used.
OC> sub testsub1 {
OC> print "The following should read \"TEST\": $testvar \n";
OC> }
you use it above.
OC> my $testvar = "TEST";
you declare it below.
and this has nothing to do with subs so your subject is misleading. that
is ok because you didn't understand the problem. any use of a variable
must be preceded by a declaration of that variable in some containing
scope. that is what strict requires (among other things). the same
problem will show up if you did this without subs.
