|0000049||Core Inform||Relations||public||2010-06-17 13:13||2010-07-01 23:07|
|Target Version||Fixed in Version||6E72|
|Summary||0000049: Can't statically store relations of values in variables|
|Description||The example source results in an I6 error:|
auto.inf(9766): Error: Expected constant but found <expression>
|Minimal Source Text To Reproduce|
Home is a room. Bijection relates various numbers to various numbers. R1 is a relation of numbers which varies. R1 is the bijection relation.
|Additional Information||Relations of objects are not affected by this problem.|
Substituting ``people'' for ``numbers,'' the significant effects on the generated I6 are:
-Rel_Record_67 (the bijection) is declared as an array instead of a global; therefore it can be used in the initializer for Global_Vars.
-The empty procedure InitialiseRelation_67 vanishes.
-Array V2V_Bitmap_67, constant V2V_Route_Cache_67, and a procedure Rel_Handler_67 are defined.
-The procedure CreateDynamicRelations becomes empty.
|Tags||No tags attached.|
|Effect||(critical) Inform 6 compiler reports errors for valid code|
|Well, perhaps it wasn't such a clever device to store the addresses of dynamically allocated relations in I6 global variables after all; it didn't occur to me that this would make them inadmissable in constant context, e.g., for initialising other variables (as here). Fixed.|
