Uniform Structured Syntax, Metaprogramming and Run-Time Compilation

Here’s our situation: there are over 100 let’s say plain text dbs, each one containing lines of different fixed-size fields ASCII format. So you can consider that each db has a schema where each field is located at a fixed offset from the beginning of the line. We have to provide subset of SQL-like operations over them, for example:

We’ll have to iterate all db entries, check the WHERE filter over each line and extract information to be returned in case it passes.
