10.1 Ada 95 Versus Ada 2005
As discussed in Section 6.1, the bindings are made to work with Ada 95 but to also take advantage of the Annex G.3 (vector-matrix) features of Ada 2005. Actually, this adaptation takes place during the PLplot build process when DHAVE_ADA_2007=OFF or DHAVE_ADA_2007=ON is chosen; the appropriate binding source files are generated automatically. User programs will work with either compiler type without modification.
10.2 GNAT Dependence
There is a slight but significant dependence on the GNAT version of Ada. This is discussed more fully in Section 6.2
The bindings include files PLplot_Auxiliary.ads and PLplot_Auxiliary.adb. These files are currently used to provide a few convenience subprograms that are used in the examples. However, they are also very tightly associated with the above-mentioned facility to accommodate either Ada 95 or Ada 2005 compilers. The current situation is such that if the user is using an Ada 95 compiler and requires the Real_Vector or Real_Matrix type definitions, then he/she should with PLplot_Auxiliary. If in doubt, PLplot_Auxiliary can always be with-ed without harm. In the future, this confusion might be removed and the need for PLplot_Auxiliary removed. (However, user programs that with it should still work without change.)
