Hi Fellow BRAHMSers I took a look at BRAG again and found that nothing had changed. I tried checking out the version with TAG start rev 1.1.1.1 and there was the same problems as reported earlier (see below). I just wanted to here if anybody ran my test example in the meantime and saw the same problems ? The test files can be picked up at : http://www.sdcc.bnl.gov/brahms/private/list_hyper/brahms-dev-l/1311.html Cheers Peter On Wed, 22 Aug 2001, Peter H. L.
