MAXScript Language Improvements
The following new features have been added to MAXScript in 3ds Max 2008:
Verbatim string literals prefixed with the '@' character are now supported and will not be expanded on evaluation even if containing escape character sequences like '\t', '\n' or '\r'.
Standard Open and Save File Dialogs
Anew historyCategory: optional keyword was added to the getOpenFilename() and getSaveFilename() methods. It allows you to specify a history category for your file dialogs.
The existing openBitMap() method now returns undefined if the bitmap cannot be loaded instead of generating a run time error.
