My last question about embedding API actually refers 2 d runtime interaction between my PIR code generator n parrot...want I am saying is that when my code generator transfers control 2 parrot(2 execute d PIR code) I want parrot not 2 display d command prompt(like we av on windows) but 2 transfer its response back 2 my code generator. Why I want this is that my compiler would come wit its output window for showing results of user-executed programs.

I would recommend that you embed parrot in whatever you are calling
your code, as a subsystem. Then your users only have to install your
(binary) application, and have no Parrot-related dependencies. If they
want to compile your code, then they will need an installed Parrot.
If you want a good example of how to embed Parrot, take a look at
PL/Parrot , which embeds Parrot in PostgreSQL.

This is an important requirement 4 my compiler. Any solution 2 this ?
