Code:
io('write','/home/run/<$name>test.log',\ $string);

In other words, lets say i have XXXXXtest.log files, such as pretest.log, aftertest.log, badtest.log. so i want to use a string call name, so i can pick which file to write in to depending on the situation. Could you please tell me how to do that?

perl::critic::profileprototype

Perl::Critic::ProfilePrototype(3)			User Contributed Perl Documentation			 Perl::Critic::ProfilePrototype(3)

NAME

       Perl::Critic::ProfilePrototype - Generate an initial Perl::Critic profile.

DESCRIPTION

       This is a helper class that generates a prototype of a Perl::Critic profile (e.g. a .perlcriticrc file.	There are no user-serviceable
       parts here.

INTERFACE SUPPORT

       This is considered to be a non-public class.  Its interface is subject to change without notice.

CONSTRUCTOR

       "new( -policies => @POLICY_OBJECTS )"
	   Returns a reference to a new "Perl::Critic::ProfilePrototype" object.

METHODS

       to_string()
	   Returns a string representation of this "ProfilePrototype".	See "OVERLOADS" for more information.

OVERLOADS

       When a Perl::Critic::ProfilePrototype is evaluated in string context, it produces a multi-line summary of the policy name, default themes,
       and default severity for each Perl::Critic::Policy object that was given to the constructor of this "ProfilePrototype".	If the Policy
       supports an additional parameters, they will also be listed (but commented-out).  The format is suitable for use as a .perlcriticrc file.
