@speed += 1 if sp.slice(8…13) == “03X16”

I’ve pulled bits 8 though 13 from my string and want  
to see if it equal 03X16 where X is number 0-9.  
Something like “grep -c 03.16 temp” would work. I’ve  
tried \d of course this did not work.

Thanks  
Jeff

@speed += 1 if (/03\d16/.match(sp.splice(8…13)))
