Another example of compatibility problems deals with MW releases.  When version
2.3 was released, I did not install the entire package at one time. I was
running a hybrid - parts were 2.2 and parts were 2.3.  According to MW, this is
OK.  (Jame Jones - please confirm.)  I went to make a new directory using
relative pathnames (.../dir/dir etc) - chd'd to it - it wasn't there.  Tried it
again - got an error - this directory already existed.  Repeated the process
using an absolute path name - everything OK.  I was busy and didn't have time
to check into it and frankly, forgot about it.  A couple of days later, I was
doing some clean-up work and went to dsave a directory elsewhere - dsave
crashed.  Same problem as I had earlier.  To make a long story short, it turned
out that the different versions of 'makdir' and 'cio' are not compatible (I
didn't know 'makdir' used 'cio' - didn't even think about it - turns out that
lots of programs use 'cio' - it is a math trap handler module).  When I went
completely to 2.3 everything was OK.  Sequel - I later found the missing
directories - they were located in the CMDS directory!

Regarding possible compatibility problems, I think that's what Frank Hogg had
in mind when he suggested forming the informal consortium.  BTW, have you
joined?
