Right here Perl interpolates $var1 and stores the complete value into $str, which is set. Essentially you are looking for an expanded use of interpolation rules based on using $var1 as if it was a reference of some type (I suppose a module/pragma might actually exist for this but I haven't seen it). > print $str; > > $var1 = "two"; > print $str; > > produce "number one, number one" to the output. But what I must to do, that > output would be > "number one, number two" ?? > In general you have to continually modify $str, for instance, my $str = "number $var1"; print $str; $str .= ", number $var1"; print $str; Obviously you could set your constant value into a separate variable so that you could change them all quickly if you want.
