a) Identify and explain the program controls which are developed to minimize errors in the
processing of records.
• Limit/reasonableness checks
Checks that data falls within predetermined reasonability. limits e.g. hours worked do
not exceed a certain limit, maybe 8 hours a day.
• Missing field check
Checks that ail essential data fields are present and are of the right length
• Edit check
This control is used to verify coding in records and to identify records that are not valid
• Sequence test of the pre-numbered documents
• Master file checks
This ensures that all codes match those on the master file e.g. employee number entered
matches the employee's number in the personnel file
• Document count
Ensures that all documents are input

b) Highlight two types of computer files which are used for the processing of data.
Master file
These contain what is referred to as standing data. They may be the equivalent of ledgers but
may also contain semi-permanent data needed to process transactions e.g. a debtors master file
will be the equivalent of debtors ledger but will also include data that in a manual system may be
kept separately such as invoicing address, discount terms and credit limits, even non-accounting
data e.g. cumulative analysis of sales to that customer.
Transaction Files
Are the equivalents of journals such as the sales journal or the purchases journal or the cashbook.
They -contain details of individual transactions, but unlike books, a transaction file is not a
cumulative record. A separate file is set up for each batch.

c) Summarize the ways in which an auditor could use file interrogation software in the
course of his/her audit work.
• Comparing information on different computer files
• Handling multiple file formats so that files located in different formats are processed
• Carrying out reconciliation of files that are maintained
• File interrogation software can also be used to re-perform calculations
• Detection of duplicated entries in the files
