Calculation of Data Within *Compare*
======================================

The *\\f* command works like the *f* command in *G7*.  The original motivation for the *\\f* command was to create variables that could be used later in the *Compare* table, or to create intermediate variables to be used in further *\\f* calculations.  

.. _COMPAREf:

**\\f <name> = <expression>**
   This command is parallel to the *f* command in *G7*.  The format is exactly the same as in *G7*.  The *\\f* command works by creating a "*Compare* workspace bank" for each simulation or databank that is being compared.  The name of each bank is of the form "CWSx.BNK", where "x" is the number of the simulation, starting at zero.  Therefore, after making a *Compare* table with simulations and using the *\\f* command in the process, there should be banks CWS0.BNK, CWS1.BNK, CWS2.BNK, and CWS3.BNK in your directory.  They will contain any series created with the *\\f* command.  When *Compare* is looking for a series, it checks first in the *Compare* workspace bank to see if the series has been put there by a *\\f* command.  Then it checks the corresponding simulation bank.
   
At present, the *Compare* workspace banks are not created until the first use of the *\\f* command, and the banks remain in use after *Compare* is finished.  The banks can be assigned within *G7* just like any other workspace bank, so you may find further uses for them beyond what originally was intended.
