[GRASSLIST:7195] Re: v.in.ascii and 6.* tables

I found out the correct syntax after some extra experimenting.
I was not sure how to cope with the category value, but saw that I need
auto-assignment of actegory number with cat=0. I then specify the value
that I wan't to interpolate as a double.
in the file:
89.1 23.5 1202.1232
cat file1.tab | v.in.ascii out=map1 x=1 y=2 cat=0 fs=space
columns='x double, y double, value double'
I then use the attribute 'value' to interpolate.
I was somewhat confused that 'x' and 'y' need to be specified again in the
columns option, but 'cat' not, although it is still a field in the
resulting dbf. But then it isn't in the inputfile, isn't it.
You were right that fs=\ is wrong, it should of course be fs=space. I was
confused with scripting syntaxes.
Thanks for your help,
