how do I?

Thinking of moving to InstallAware studio fromn IS11.
1. Set the length of a (string) variable? I'm passing a string variable through to a dll which will update the string, thus the string needs to be made long enough before passing it to the DLL. getting bored with having to to use set varaible FRED to 12345678901234567890blahblah...
2. Is it possible to pass the MSIHANDLE of the executing script through to a Delphi DLL and if it is, can we use this to access the session and update session variables as you can with IS and WIse?
Product looks nice, looking at it after seeing Borland make the switch.

You can call any arbitrary DLL using Call DLL Function and have it write to any arbitrary script variable. OR, you can build a custom Delphi plug-in which obtains a full list of available variables in the script, and participates in MSIcode as a native citizen. There is even a pre-built Delphi plug-in sample that you can use.
