Hi...
I have some data from a file...
example:
file start
10.5 30.5 40.8 57.9 90.8

end of file
I would like to read these data from a file, and these should be placed
in a array...
But when I read the file the datas are placed in a string. How do i get
these data converted to a array?

Thanx
Martin Skou

Dear Martin,

We have a general routine which reads automaticly array orientated files
like

HEADER
HEADER
COLUMN1 COLUMN2 COLUMN3 COLUMN4 COLUMN5
10.5 30.5 40.8 57.9 90.8
10.5 30.5 40.8 57.9 90.8
10.5 30.5 40.8 57.9 90.8
TRAILER
TRAILER

You can have as much header or trailer comments you like. This routines
founds automaticly where the data starts and where the data is finished.

result=read_data_file(file.txt)

The result could have these tags

header
separator
data
trailer

The data tag is an array of columns, lines. The type could be set.
A widget to look at the data could be called by a keyword.
