Re: Stream output, thanks Jang, but...



Hi Paulo,

There are a couple of work-arounds that might do what you're after:

Work-around 1:
	yes? REPEAT/J=hi:lo:-1 list/file=bin.file/APPEND/format=stream myvar

Work-around 2:
	yes? SAVE/FILE=temp.cdf myvar
	... now use ncdump and an editor and reverse the order of the Y axis
		coordinates. Then ncgen to renerate temp_rev.cdf
	yes? use temp_rev.cdf
	yes? list/file=bin.file/format=stream myvar

Note that V.5 of Ferret will have the capability to reverse an axis. V.5
is scheduled for release in April.
