1 is the number of elements in the list.

This line:

@A = join( "," .....

[download]

Creates a single element that is a string containing a bunch of comma delimited data.

This line:

$A = @A;

[download]

Evaluates @A in scalar context, which causes Perl to assign a count of the number of elements in @A to $A.

Those issues will be discussed in perlintro, and join.

In particular, the purpose of join is to turn a list into a single scalar value.
