Re: strange question on defining BAD value

[Mick Spillane <spillane@xxxxxxxxxxxxx>]

hi gnzeng,
	ferret is expecting your "def var" command to actually define
the function or source of values for the variable uv. for example
	def var/bad=3 uv=i
	list/i=1:5 uv
 1   / 1:  1.000
 2   / 2:  2.000
 3   / 3:   ....
 4   / 4:  4.000
 5   / 5:  5.000

if you want to set the missing value code for an existing variable
(perhaps read in from a data file) you can use the "SET VAR" command
for example
	file/form=free/var=uv data.file
	set var/bad=99.9 uv

good luck,
mick
