issue-#43 revisited (unlimited size of code procedures)

[Ivan Denisov]

Some time ago we made size of code procedures unlimited.
Josef is suggesting some improvements for this solution described bellow.

Although currently not used in BB itself, string literals may
appear in a code procedure indeed. The change for the representation
of code procedures must also be applied for string literals.
In addition:
1. It is now possible to have any number of string literals
as specified in the docu.
2. Usage of real constants inside a code procedure is marked as an error now.
3. the readability of the code has been slightly improved
