5 /* The following boolean constants follow a naming convention. Each
6 constant gives a name for a boolean expression. For example,
7 ver_le_9_1 represents version <= 9 and release <= 1
8 ver_le_10_2 represents version <= 10 and release <= 2
9 ver_le_10 represents version <= 10
10
11 A typical usage of these boolean constants is
12
13 $if dbms_db_version.ver_le_10 $then
14 version 10 and ealier code
15 $elsif dbms_db_version.ver_le_11 $then
16 version 11 code
17 $else
18 version 12 and later code
19 $end
20
21 This code structure will protect any reference to the code
22 for version 12. It also prevents the controlling package
23 constant dbms_db_version.ver_le_11 from being referenced
24 when the program is compiled under version 10. A similar
25 observation applies to version 11. This scheme works even
26 though the static constant ver_le_11 is not defined in
27 version 10 database because conditional compilation protects
28 the $elsif from evaluation if the dbms_db_version.ver_le_10 is
29 TRUE.
