Closing files

Because the number of possible file handles is restricted in OS/2 
sessions, you should always close every file you've opened as soon as 
possible. You also need to close a file (and perhaps reopen it again) if 
you want to call another program to write into or read from this file. 

You should only use 

 
  rc = <STREAM( filename , "c", "CLOSE" )

to close a file. The other method that is sometimes used, using <LINEOUT 
or <CHAROUT without the second parameter, is only valid for files to which 
you have write access (even if you've only read from the file) (?).
