PL SQL Values of a variable need to be cleared or reset to default

Question

Hi I've a variable as follows,

T_ID_LIGNE TBL_ID_LIGNE;

Later I'm loading some data into this variable, performing operations with the data in it. Now I need to clear the data in it and load fresh data. I don't want to use any extra variable.

Is is possible?

Please help

Thanks.
