There is a bug when using a penstyle other than 0 for single data sets
in plot
a=. i.5
'type line' plot a;a
'type line; penstyle 0' plot a;a
'type line; penstyle 1' plot a;a
The first two plot commands work fine, but the third crashes J and gives
repeated lines of "unsupported: -2000" in the ijx window. Interestingly,
doubling up on a line will avoid the problem:
'penstyle 1' plot a
will crash, but
'penstyle 1' plot 2 5$a
gives the desired dashed line.
