This code should continue to work in R2012b. Can you give more details
about what's going wrong, and in what context? I just tried this in
R2012b, and it worked as I expected:

>> matlabpool open local 3
>> fnameroot = 'foo';
>> spmd, t = getCurrentTask; id = num2str(t.ID); fname = ['foo' filesep 'log_' id '.log'], end
Lab 1:
  fname =
  foo/log_1.log
Lab 2:
  fname =
  foo/log_2.log
Lab 3:
  fname =
  foo/log_3.log
