How to open mutliple HTMLHelp files at the same time using Delphi. |

In Delphi, the application's main help file is assigned through the TApplication.HelpFile property. All calls to the application's help system then use this property (in conjunction with CurrentHelpFile) to determine the help file to which help calls should be routed.

I don't know if either are necessarily better, but two *alternate* ways would be:

Patrick is correct, the only way you can really do this is to use an explicit stack in your interpreter, and hoist the appropriate segment of stack into the heap when you need to convert to a continuation.
This is basically the same as what is needed to support closures in languages that support them (closures and c... |
This has a lot to do with covariance, e.g., generic types are considered as parameters, and if the parameters do not resolve properly to a more specific type then the operation fails.

I would personally recommend us erubis in precompiled templates.
