How read data onto an array

Hallo to all

some simple task is just not working:
I need to read some coordinates to an array using ksh script. Until now I tried this:

points=`cat $inputfile | grep ... | cut ... `
------- example ---------------------
echo $points # trace only
-0.00000000000052 229.37500000000000 -86.20000000000000 291.90000000000000 0.00000000000367 -86.20000000000000 281.27957
5308520 210.960466611540 (etc...)
----- end of example -----------------
now I used to go on like this:
set -A array $points

but then I get this error message:
-0.00000000000052: A specified flag is not valid for this command.

If I eliminate all "-" signs from $inputfile then the script works fine to the end.

I want to have the result as:
$array[0] -0.00000000000052
$array[1] 229.37500000000000
$array[2] -86.20000000000000

How can I get the above results even with negative numbers ?

thanks for any advises

Hi Klaus,

You need to use:

set -A array -- $points

to indicate "end of arguments, beginning of data".

Hi,

I use /sbin/sh and it works fine with

set -A array $points
