Subject: [ruby-talk:30047] Re: string variable within a string

My fault, the numbers 720 and 735 are returned from the TCP Server as
strings, so to put them into a  send string to be sent back to the
server in a following send string I created new integer variables 
using   var.to_i

so....
x = v.to_i
y = v1.to_i
t.send(/gettext(#{x},#{y},0)\n",0) works fine

thanks

Paul
