
Add the Process Description, “Accumulate
the hardware subtotals. These include the
number of machines for each hardware
brand.”
E–3
Modify and print the CONFIRM COMPUTER DELETION Process
entry. Add the following Process Description:
Use the
COMPUTER RECORD to format the Deletion Confirmation
screen (refer to the Delete computer Prototype screen).
Prompt the user to click the OK button to confirm the
deletion; otherwise, click the Cancel button to cancel the
deletion. If the operator clicks OK to delete the record, delete
the record and display a
“Record Deleted” message;
otherwise, display a “Deletion Canceled” message.

E–6
Produce process specifications for process 3.1.7, FIND
MATCHING HARDWARE RECORD. This process is part of a
program producing a report showing all computers on which
each software package is located. Use Visible Analyst to view
data flow diagram 9.7. Use structured English to depict the
following logic: For each SOFTWARE RECORD, loop while there
is a matching hardware inventory number. Within the loop,
accomplish the following tasks:
Randomly read the
COMPUTER MASTER file. If a record is found, format the
MATCHINGCOMPUTERRECORD information. If no record is
found, format a NO MATCHING error line. Furthermore, if the
found COMPUTER RECORD is inactive, indicating that it has
been removed from service, format an INACTIVE MATCHING
COMPUTER error line
