We are having difficult running the mvis program, specifically the use of
the [weight] command. We invoke mvis as prescribed but, when we insert the
weight command [weighttype=varname], the program errors out with the
message that "fweight not found". When we set trace on to see what's up,
the program moves through to _mvis and then errors out. To our untutored
eyes, it appears that _mvis is stripping out the brackets and the reading
fweight as a variable. The program errors out regardless of the weight type
we invoke. Otherwise, minus the weight command, mvis works fine. If anyone
can help on this, it would be greatly appreciated. Thanks.
