assign a command line argument and a unix command to awk variables

Hi ,

I have a piece of code ...wherein I need to assign the following ...
1) A command line argument to a variable
e.g origCount=ARGV[0]
2) A unix command to a variable
e.g result=`wc -l testFile.txt`

in my awk shell script

When I do this :
print "origCount" origCount --> I get the output as origCountawk
and I get a syntax error for 2)

Can you please help me with both

Thanks
