Presumably, you are looking to use Perl to manipulate the source code of some assembler like language?

If so, the answer is yes. It would be a relatively simply s/// substitution.

But, in order to help you, you'll have to more clearly define

  • the circumstances under when that substitution to take place;

    Is it whenever the text ROUTINE#2 occurs (other than its definition)?

    Or only when it appears as the second parameter to the EX instruction?

    Only when it is the second argument and R1 is the first?

  • the scope of the substitutions;

    Is this all contained in one file? Multiple files?

  • Much more information.

That said, whilst it could certainly be done with Perl, you may be better off using a proper macro processor like M4 or even a C pre-compiler.

Clearer questions lead to better answers -- and stop people misinterpreting the questions.

The start of some sanity?
