I was actually looking at this when I was doing my port of BASH for the CBT. But I've basically abandoned my port since Rocket Software took over the ported tools from IBM. I figured that they'd do a better job than I. BASH does some really strange things to run commands. It's not a simple fork()/exec() sequence which would be relatively simple to replace with a spawn(), which is required to honor _BPXAS_SHAREAS. > > Kirk Wolf > Dovetailed Technologies > http://dovetail.com > > -- Heisenberg may have been here.
