$title 'Refactor suite test 5' (REFACT05,SEQ=666)

$onText
This test is the fifth one of the refactor suite. This is a quantitative test
of writing/reading a workfile with many instruction.
There is an expected sequence when using this test:

1. Run this test with command line option "--before=True"
2. Modify and rebuild cmex
3. Run this test without command line option
