-# Putting part of the query into a separate file
+# EXPORT and IMPORT
 
-Here's the mechanism for putting part of the query into a separate attached file:
+A mechanism for putting part of the query into a separate attached file. To use the mechanism, you need to set the following pragma in the query:
 
-* [PRAGMA Library](pragma.md#library) marks the attached file as available for import.
+* [PRAGMA Library](pragma.md#library) — marks the attached file as available for import.

-* `EXPORT $my_symbol1, $my_symbol2, ...;` lists the names of named expressions in the library that are available for import.

-* `IMPORT my_library SYMBOLS $my_symbol1, $my_symbol2, ...;` makes the listed named expressions available for further use.
