Suprtool as a Database Integrity Tool.

Financial transactions are often processed in batches. Between jobs aborting,
program bugs, and less-than-careful data fixes by MIS staff, these batches can
get out-of-balance. Using the Total command can quickly verify that all
transactions net to zero.

Do the debits equal the credits?

    :run suprtool.pub.robelle
    >base     fms.gl,5,reader
    >get      d-transactions
    >output   $null
    >total    trans-amt
    >xeq

    Totals (SUN, JAN 29, 1995,  2:56 PM):
    TRANS-AMT                           81451+
    IN=6, OUT=6. CPU-Sec=1. Wall-Sec=1.

By default the results of the Total command are displayed on the screen
($STDLIST), but can be appended to the output file. To do, this you need to
turn Set Squeeze Off and add a new Total command as follows:

   total $file filename,append

Up to 15 fields can be totalled in each pass.
