Welcome to the forums. It would certainly help if you showed us the script. man csh says

LIMITATIONS
       Words can be no longer than 1024 characters.

       The system limits argument lists to 10240 characters.

       The  number  of arguments to a command which involves filename expansion
       is limited to 1/6th the number of  characters  allowed  in  an  argument
       list.

       Command substitutions may substitute no more characters than are allowed
       in an argument list.

       To detect looping, the shell restricts the number of alias substitutions
       on a single line to 20.

Also, see this link - 1992: SUMMARY: How many is too many words to csh?

Please read and understand what the man page says.
The man page description says the system limits argument list to 10240 characters. You say you have 2000 entries and assuming each date entry is of the form xx-xx-xx i.e. 8 characters, the argument list computes to atleast 2000 * 8 + 1999 * 1 (whitespace) characters. If my assumptions and calculations are right, then that number is way above 10240.

Anyways, why a for loop when awk alone can do it ? I think this should work as well.

awk -F'-' '{print $3"/"$1"/"$2}' /home/priyank/try_2/data3/date.txt >> /home/priyank/try_2/data3/cool.txt

I hope this is no homework question.
