[Gretl-users] gretl freezes

Dear list members, I encounter a problem when I try to run a script that contains several (i.e. 4) loops. The structure is quite simple like loop i=1..cols(matrix_x) do some stuff loop k=1..cols(matrix_y) do some other stuff loop t=start..end loop j=1..5 estimate model endloop endloop do some further stuff endloop endloop If necessary, I am happy to provide more details on the script. Whenever I try to run that script, the script output prints the code and stops without an error message. After this occured, not even the simplest operation like scalar s = 1+1 runs correctly. The only thing that happens is that the script output occurs, which shows the code but does not come up with the results. The strange thing is, the loop structures works without a problem when I use the three "inner" loops. loop k=1..cols(matrix_y) do some other stuff loop t=start..end loop j=1..5 estimate model endloop endloop do some further stuff endloop The fourth loop is only intended to setup a different matrix in each loop and at the end concatenates some vectors to the created matrix. I use Gretl 1.9.92 win32. CPU: Intel Core i7, 2.8 GHz RAM 8 GB Windows (8.1 pro) is 64-bit Does anyone have a clue what went wrong? Thanks in advance, Jan
