PROGRAM 3: Error 54 handled by system
CHARACTERISTICS: ynny
OPERATOR SCRIPT:
See OPERATOR SCRIPT for Program 1.
DESIGN:
Throughout this program, every time an error is signalled, the system-defined
error handler should call <error logging> to write in error message on
the error file.
Also, throughout this program, this is what is meant by
"operator verifies error nmessage":
display next error message in error file to operator
OPQA/according to the error message, which function generated the error?
if (operator response = expected function) then
OPQA/if error message identifies error code, enter it, else "n"
if (operator response = "n") then
display standard error wording(s) to operator
OPQA/does error meaage match standard wording?
pass/fail depending on (operator response = yes)
else
pass/fail depending on (operator response = expected code)
endif
else
fail
informative message on missing/incorrect function
endif
Not open workstation with workstation identifier wkid to test if
functions 3,4,5,64,67,68,73,83,85,112 with workstation identifier wkid
generate error 54: ignoring function, the specified workstation is not open.
Then open workstation with wkid to test if function 4,6,67,87,111 with
workstation identifier wkid+1 generate error 54.
