Set a variable from awk output - RESOLVED

I have a file which I am processing using awk to spit out the following:

Code:
export CLIENT=1 ; export USER=1 ; export METABASE=1 ; export TASK=1 ; export TOTAL=3

What i want to do now is execute that within the script so those variables are available to other commands. I've tried piping the output to ksh (but obviously thats only for the existance of the ksh being called. I've tried some variations of ` and $(()) $( ) of the output but can't seem to get it to work. Any ideas?

Thanks

one idea
Code:
shell$ . ./script_that_exports_vars

there's a space between the two dots

andryk, I could write the awk output to a temp file and then execute this generate script, but I was trying to avoid the use of temporary files if possible.

sorted!

Code:
eval `awk < file ' { print "export TESTVAR=" $1 } '`

forgot about eval!!!
