pascalscript - Using global string script variable in Run or other section in Inno Setup

Question

I need a global string variable in Inno Setup, that is going to be initialized in [Code] section and used in [Run] section.

Is this possible?

Answer 1

You are probably looking for a scripted constant:

[Run]
Filename: "{app}MyProg.exe"; Parameters: "{code:GetGlobalVariable}"

[Code]

var
  GlobalVariable: string;

function GetGlobalVariable(Param: string): String;
begin
  Result := GlobalVariable;
end;

function InitializeSetup(): Boolean;
begin
  GlobalVariable := '/parameter';

  Result := True;
end;
