Alternatively, if there are a lot of print statements that you'd have to change, you can print to a scalar variable. All you have to do is call open like so:

open(FH, ">", \$var);

After that, you can print to FH and the results will be accumulated in $var, which you can then use the options presented by the monks that responded before me. This all assumes a fairly recent version of perl (I don't know exactly when this feature was added).
