Abstract
Semi-Automatic Number Verification (SNV) on an electronic adding machine employing a small amount of random access memory (RAM), a microprocessor, a printer link and printer, a piezo-electric speaker to facilitate conventional adding machine capabilities with the additional SNV feature employing an enable/disable (SNV) button. A keypunch operator depresses the SNV key to start the SNV process entering numbers with either the plus (+) or minus (-) key, entered appropriately into the RAM, and particularly an RAM module including first and second series arrays and first and second counters. When the operator depresses the TOTAL key, the printer is enabled, if it is currently switched on. The operator then enters the second series of numbers and the microprocessor compares the values to those stored in the RAM module. If a discrepancy is detected, the adding machine enters an edit mode in which the operator need only look at the original source document and the display for verification of entries.
