[comp.sys.apollo] Pascal Change in SR9.5

srt@CS.UCLA.EDU (06/29/87)

I don't know whether or not this has been documented, but under SR9.5,
an I/O results if you try to open a file that has previously been 
opened but not closed.  In earlier SRs, you could open a file for 
reading and then later open it again.
