Welcome to the forum.
Please read and follow How to use [code] tags and make your code easier to read?

That's an infinite loop.
It needs an exit statement.
Also you appear to be doing nothing with the data read from the file. What's str_data exactly?

I assume the Declare section exists but has been left out of the post, otherwise it just wouldn't compile.
The OP does really need to post it
