I can't figure out why this program hangs? how to fix it?

Two things I noticed.

Your LINE label is immediately followed by data definitions which the CPU will try to execute. Ideally your data should be outside of any place where instructions are expected.
Returning from the program with RET might be okay, but usually something like INT 0x20 is preferred and more robust.
