| 33 -- Standard (where we have no opportunity to build image tables), and in | |
| 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 -- Note: this is an obsolete package, replaced by System.Img_Enum_New, which | |
| 38 -- provides procedures instead of functions for these enumeration image calls. | |
| 39 -- The reason we maintain this package is that when bootstrapping with old | |
| 40 -- compilers, the old compiler will search for this unit, expecting to find | |
| 41 -- these functions. The new compiler will search for procedures in the new | |
| 42 -- version of the unit. | |

| 56 -- literals concatenated together in sequence. Indexes is the address of an | |
| 57 -- array of type array (0 .. N) of Natural_8, where N is the number of | |
| 58 -- enumeration literals in the type. The Indexes values are the starting | |
| 59 -- subscript of each enumeration literal, indexed by Pos values, with an | |
| 60 -- extra entry at the end containing Names'Length + 1. The reason that | |
| 61 -- Indexes is passed by address is that the actual type is created on the | |
