Script Logic - Internal Table/Fields for Calculations

Hi all,

Say I wanted to get the value of this statement below and record it to an internal account to use further down in the calculation, but not have the value actually stored in the database, is that possible?

Example is this:

*XDIM_MEMBERSET REVACCT = RENEWAL_ACV, RNW_CHURN_RT,AVG_CNTRCT_LENGTH_RENEWALS

*FACTOR REVACCT = (1 - RNW_CHURN_RT), RENEWAL_ACV

*REC KNWN_FIRST_RNW_ACV, KNWN_FIRST_RNW_Bill_1, KNWN_FIRST_RNW_TCV

I want to multiply (1- RNW_CHURN_RT)  *  RENEWAL_ACV, and I want to store (1- RNW_CHURN_RT) in an internal field for future calculation in this script.

Is that possible?

Thanks.
