Hey mark,

No other instance should access that file. The primary shell gets a .000, the 
first 2ndary shell gets a .001, the next a .002 and so forth.

I think it was new to 6.0. Before that I don't know if it was just an internal 
command, or didn't exist. I don't reacall.

I don't recall that and I used 4DOS and 4OS2 a lot under OS/2. Who knows.
