The pages on this site contain documentation for very old MS-DOS software, purely for historical purposes. If you're looking for up-to-date documentation, particularly for programming, you should not rely on the information found here, as it will be woefully out of date.

  Syntax: void CopyStream( PFILE pfSource, PFILE pfDest,
                           COL xStart, LINE yStart,
                           COL xEnd,   LINE yEnd,
                           COL xDest,  LINE yDest );
 
  See:    CopyBox, CopyLine, ◄Processing Text►
 
     CopyStream copies a stream of text, including line breaks, from one
     file to another.
 
     The source and destination files are specified by <pfSource> and
     <pfDest>. If <pfSource> is PNULL, a stream of blanks is inserted.
 
     These arguments define the stream to be copied:
 
     Argument     Position
 
     <xStart>     First character
     <yStart>     First line
     <xEnd>       Position immediately after the last character
     <yEnd>       Last line
 
     The text is inserted into the destination file just before the
     location specified by <xDest> and <yDest>.
 
     The same file cannot serve as both source and destination.
 
     If the copied stream has colors, they are copied with the text.
