The flaw is here:

counter=+1

You are setting counter equal to +1 when you mean to increment it.

Try:

counter += 1 # notice the + is to the left of the =

Also, you are never incrementing counter1, so perhaps the code should  
look like this:

c=File.dirname("directory.rb")
direc=Dir.entries(c)
b= Regexp.new(/tlb/)
counter,counter1=0,0
array=[]
while(counter<direc.length)
   if (direc[counter]=~b)
     puts direc[counter]
     array[counter1]=direc[counter]
     counter1 += 1
   end
   counter += 1
end
