Variable Sized Array Length Question

I need to implement the following logic and need some expert help from UNIX community.

These are the steps in my Shell script.

1. Analyze a file.
2. Extract all the ID's in that file.
3. Use the ID's from #2 to run another filter on the file.

I've implemented # 1 and 2 using shell / perl scripts.
My problem is that the # of ID's can vary from each run. How can I grep with a variable sized array?

For example, my first run would be:
ID's = <id1, id2, id3>
cat <file1> | grep <id1, id2, id3>

for second run, this would look like:
ID's = <id1, id2, id3, ... id60>
cat <file1> | grep <id1 ... id60>

thank you,
Kalpesh
