Snippit needed

given some option variables

c1 = 0
c2 = 0
c3 = 0
c4 = 0

given a string (a set of pairs of options) which could be read from 
MYSQL or a file

paramString =  '"c1" 0 "c3" 1 "c2" "y" "c4" "v"'

such that:

c1 = 0
c2 = "y"
c3 = 1
and c4 = "v"

at the end of the procedure.

I just can't figure out how to do this with RUBY.

Thanks

Tom Reilly
