How can I use macros in Perl?

Question

How do I use macros in Perl, like I do in C?

Example:

#define value 100 
print value; 

I want to get the output as 100.

Answer 1

Try the following:

macro.pl

    use strict;
    use warnings;
    #define a 10;
    print a;

And run this code using -P switch.

Example: perl -P macro.pl

And use the module Filter::cpp also.
