Subject: syntax error, unexpected '}', expecting kEND

I'm using ruby 1.8.6 (2010-02-04 patchlevel 398) [i386-mingw32], WinXP
and Notepad++ in the Unix mode (for line endings)

I have the following code:

q = [1.0, 4.0, 10.0, 27.0, 50.0, 600.0, 1000.0, 5833.0, 6250.0,
1500000.0]
x = q.each{|e| print Math.log10(e).to_i, " "}
p x
r = q.collect{|e| Math.log10(e).to_i}
p r
q.inject(Array.new(4,0)){ |h,e| if e < 10000 then h[Math.log10(e).to_i]
+=1 }

i=0
q.inject(Array.new(4,0)) do |h,e|
  if e < 10000 then h[r[i]] += 1
  i += 1
end

The first 5 lines work as expected.  However, the first q.inject line
and the q.inject block give the following errors:

D:\abc>ruby doh2.rb
doh2.rb:6: syntax error, unexpected '}', expecting kEND
doh2.rb:12: syntax error, unexpected $end, expecting kEND


My goal is to take the numbers in q and count how many are in the ranges
1-9, 10-99, 100-999 and 1000-9999.

I thought maybe it was using the Math.log10 expression as an array
index, hence the second q.inject code.

I have looked at an octal dump.  No surprises there.

0000000   q       =       [   1   .   0   ,       4   .   0   ,       1
0000020   0   .   0   ,       2   7   .   0   ,       5   0   .   0   ,

0000060   5   8   3   3   .   0   ,       6   2   5   0   .   0   ,

0000240   i   }  \n   p       r  \n   q   .   i   n   j   e   c   t   (
0000260   A   r   r   a   y   .   n   e   w   (   4   ,   0   )   )   {
0000300       |   h   ,   e   |       i   f       e       <       1   0
0000320   0   0   0       t   h   e   n       h   [   M   a   t   h   .
0000340   l   o   g   1   0   (   e   )   .   t   o   _   i   ]       +
0000360   =   1       }  \n  \n   i   =   0  \n   q   .   i   n   j   e
0000400   c   t   (   A   r   r   a   y   .   n   e   w   (   4   ,   0
0000420   )   )       d   o       |   h   ,   e   |  \n  \t   i   f
0000440   e       <       1   0   0   0   0       t   h   e   n       h
0000460   [   r   [   i   ]   ]       +   =       1  \n  \t   i       +
0000500   =       1  \n   e   n   d  \n
0000510

Any ideas as to what is going on here?  I have also tried other inject
statements that I know used to work, but they don't now.  Is inject
broken in my version?

Thanks,
Louise
