IOResult and {$I-/+} are Borland Pascal/Delphi compatibility issues. It 
stands to reason that expect that anyone who wants to use non-standard 
features (i.e., Borland Pascal/Delphi features) would have sufficient 
knowledge of Borland Pascal/Delphi to appreciate how those features are 
meant to be used. 

This is a historical factor, and there was no need to duplicate 
features that Borland already documented well, and which were well 
known to Borland Pascal/Delphi programmers.

Perhaps someone should now duplicate that information - but I doubt 
whether it would be a sensible use of anyone's time. Just find the 
Borland Pascal and Delphi help files (freely available on the net), and 
you would find full documentation of these features.
