Re^4: SAMPLE IS NOT GETTING OPTIMIZED AT ALL...

Dear Sir,
I have failed to find DLC=.t. in the sample file I attached. Please could you make the change in the file and send it to me? I even went through the suggested thread, but could not find a sample file. DLC comes under $zmat as I have checked from the manual. Please help.
Thank you Alex Sir for Firefly version 8. Your efforts are highly valued. This new file will work on Firefly8 now. :)

Regards,

>>Dear Prof. Alex,

>>And when I change the memory value to the above value..then also problem isnt't resolved, infact it gives some other memory value.....Is there a bug or something? Please tell me what is happening? I have been stuck up to this since last one month. I have tried differnt PC systems too. Please help.

In addition I would say that it is really taking long to optimize it. Could you throw some light on how to make it faster?
