Hi,

you can run ". PARAMETERS; set" with popen. Then read stdin and
parse the lines:

The lines from stdin look like this:

ACLOCAL_PATH=/opt/gnome/share/aclocal
BASH=/bin/bash
BASH_VERSINFO=([0]="2" [1]="05b" [2]="0" [3]="1" [4]="release" [5]="i586-suse-linux")
BASH_VERSION='2.05b.0(1)-release'
COLORTERM=1
COLUMNS=143
CPU=i686
CVSROOT=:ext:tguettler at homeserver:/raid/develop
CVS_RSH=ssh
 ....

you could use '^(.*?)=(.*)$' as regex to parse each line
group(1) is the variable name group(2) the value.

 HTH,
   Thomas
