[SOLVED] Capturing output in a korn variable
Hi, I'm new to korn and having trouble capturing the text output from one program in an array that I can then feed into another program. Direct approaches didn't work, so I've tried to break it down thus:

The program lonlat2pixline gives the values I need in the second column, so I print that column with awk:

Code:
$ lonlat2pixline -x 2 -y 2 $afile $lon $lat | awk -F= '{print $2}'
-159.814606
24.181808
474
478
342
346

Now I try to capture those numbers in a variable:

Code:
$ output=$(lonlat2pixline -x 2 -y 2 $afile $lon $lat | awk -F= '{print $2}')
$ echo $output
-159.814606 24.181808 474 478 342 346

Unfortunately, this is not an array yet, but a scalar. I therefore try to make it into an array using set -A:

Code:
$ set -A outarray $output

...and I get the following error:

Code:
ksh: set: -1: unknown option
ksh: set: -5: unknown option
ksh: set: -9: unknown option
ksh: set: -.: unknown option
ksh: set: -8: unknown option
ksh: set: -1: unknown option
ksh: set: -4: unknown option
ksh: set: -6: unknown option
ksh: set: -0: unknown option
ksh: set: -6: unknown option
Usage: set [-sabefhkmnprtuvxBCGH] [-A name] [-o[option]] [arg ...]
$

Thanks in advance.
