I faced an example where in a loop:
if (\$base2\)
You probably say
if (/$base2/) { ... }
The /.../ is a pattern match. It's shorthand for
if ($_ =~ /$base2/) { ... }
which treats $base2 like a regular expression (pattern) and tries to find
a substring in $_ which matches that pattern. See 'perldoc perlretut' for
more information on regexes.
The code was probably something like
for (@dna) {
if (/$base2/) {
...
}
}
which iterates over the values in @dna and does something for each value
that contains $base2.
