| 34 -- package System (where it is too early to start building image tables). | |
| 35 -- Special routines exist for the enumeration types in these packages. | |
| 36 | |
| 37 -- This is the new version of the package, for use by compilers built after | |
| 38 -- Nov 21st, 2007, which provides procedures that avoid using the secondary | |
| 39 -- stack. The original package System.Img_Enum is maintained in the sources | |
| 40 -- for bootstrapping with older versions of the compiler which expect to find | |
| 41 -- functions in this package. | |

| 55 -- other than those defined in package Standard. Names is a string with | |
| 56 -- a lower bound of 1 containing the characters of all the enumeration | |
| 57 -- literals concatenated together in sequence. Indexes is the address of | |
| 58 -- an array of type array (0 .. N) of Natural_8, where N is the number of | |
| 59 -- enumeration literals in the type. The Indexes values are the starting | |
| 60 -- subscript of each enumeration literal, indexed by Pos values, with an | |
| 61 -- extra entry at the end containing Names'Length + 1. The reason that | |
| 62 -- Indexes is passed by address is that the actual type is created on the | |
| 63 -- fly by the expander. The desired 'Image value is stored in S (1 .. P) | |
| 64 -- and P is set on return. The caller guarantees that S is long enough to | |
