I would like to be able to structure my code for my Inno Setup project but I am forced to move code around because you can't call a function unless it is defined first.
Is there a way to declare a prototype at the top so that I don't get the "Unknown identifier" error and so that I can structure my code in logical blocks.
In Pascal (including a Pascal Script used in Inno Setup), you can define a function prototype (aka forward declaration) using a forward keyword:
procedure ProcA(ParamA: Integer); forward;
procedure ProcB;
begin
ProcA(1);
end;
procedure ProcA(ParamA: Integer);
begin
// some code
end;
