Inno-setup：找不到功能？
我正在尝试使用 Pascal 脚本构建一个脚本来返回文件夹的名称（但我想稍后使用相同的函数来获得更广泛的结果）。 我的脚本在这里：
;This is a test script
#define MySourceDir "D:\Temp\InnoTestSrc"
#define MyDestDir "D:\Temp\InnoTest"
[Setup]
DefaultDirName={#MyDestDir}
DisableDirPage=no
AppName="MyTestApp"
AppVersion=1
[Code]
function GetMyConstant(Param: String): String;
var
strConst: string;
begin
strConst := '{#' + Param + '}';
MsgBox(strConst, mbInformation, MB_OK);
Result := expandconstant(strConst);
end;
function GetDataDir(Param: String): String;
begin
{ Return the selected DataDir }
Result := 'DummyString';
end;
[Files]
Source: {#MySourceDir}\TestFile.pdf; DestDir: {code: GetDataDir}
但是，当我尝试编译它时，我收到
编译错误！ 线路：29 错误：找不到所需的函数或过程“GetDataDir”。
我试图理解为什么编译器找不到该函数，但我不明白。 任何对我的（可能是明显的）错误的帮助将不胜感激
I am trying to build a script using Pascal scripting to return the name of a folder (but I want later to use the same function for wider results).
My scrip is here:
;This is a test script
#define MySourceDir "D:\Temp\InnoTestSrc"
#define MyDestDir "D:\Temp\InnoTest"
[Setup]
DefaultDirName={#MyDestDir}
DisableDirPage=no
AppName="MyTestApp"
AppVersion=1
[Code]
function GetMyConstant(Param: String): String;
var
strConst: string;
begin
strConst := '{#' + Param + '}';
MsgBox(strConst, mbInformation, MB_OK);
Result := expandconstant(strConst);
end;
function GetDataDir(Param: String): String;
begin
{ Return the selected DataDir }
Result := 'DummyString';
end;
[Files]
Source: {#MySourceDir}\TestFile.pdf; DestDir: {code: GetDataDir}
However, when I try to compile it, I get
Compile Error!
Line: 29
Error: Required function or procedure ' GetDataDir' not found.
I am trying to understand why the compiler cannot find the function, but I do not understand.
Any help to my (probably obvious) error would be highly appreciated

如果你这样做的话有效吗
？我认为确实如此。事实上，您应该听编译器的意见，它说没有名为
GetDataDir GetDataDir！Does it work if you do
instead? I think it does. Indeed, you should listen to the compiler, which says that there is no function called
<space>GetDataDir. Of course there is not! Your function is calledGetDataDir!
