All,
I am really bad at REGEX's and am in need of help!
I have a script that asks for users input but I need to check that the input
begin with "MDS(and a number 0-9)" before proceeding

below is something like what I am doing:

print "ask for input";
chomp ($answer=<STDIN>);
#(not sure which one to use below)
while/unless/if
  $answer does not begin with "MDS[0-9] (and a number 0-9)
 { keep asking for answer };

TYIA
