From Rosetta Code

**Library**

This is an example of a library. You may see a list of other libraries used on Rosetta Code at Category:Solutions by Library.

**ALGOL 68-Primes** is a set of prime related routines and operators for use in Algol 68 programs.

To use this in a program, copy the source code from the Talk page to a text file called *primes.incl.a68*, putting it in the same directory as the importing program.

Then add `PR read "primes.incl.a68" PR`

to the source of the program.

If you are using ALGOL_68G or another compiler/interpreter that supports the read pragmatic comment, then the program can be run as usual.

For other compilers, the ALGOL 68 pre-processor in Compiler/Simple file inclusion pre processor can be used (see the instructions on that page).
