rem This is the Vendor Information Entry Sort Program
rem This program creates a backup file and copies all undeleted
rem records to that file. Simultaneously it creates a RAM resident
rem list of either tag numbers, account numbers, or reference numbers
rem - S(xxxx) - and Relative Record KEYS - T(xxxx).
rem The tag, account, or reference numbers are then sorted via a Shell
rem Metzler algorithm and the Relative Record KEYS carried along.
rem When the sort is complete, the Relative Record KEYS are used to
rem restore the backed up records to the original file in sorted order.
