PROGRAM 7: Error 7 handled by system
CHARACTERISTICS: nnny
OPERATOR SCRIPT:
See OPERATOR SCRIPT for Program 1.
DESIGN:
Throughout this program, every time an error is signalled (as noted by
the tag "signals error"), the system-defined error handler should call
<error logging> at least once to write an error message on the error file.
Not open archive file after initializing to test if function
115,116, 120,121,123,124,126 generates error 7 and/or 404:
ignoring function, function requires state (PHOP, *, *, AROP).

"If <close archive file> signals an error because PHIGS is
open but no archive file is open, it should not cause any
other effect."

open but no archive file is open, it should not cause any
other effect."

<retrieve structures> with arid, stlist : signals error
<retrieve all structures> with arid : signals error
TEST: #SR 7
"If <retrieve all structures> signals an error because PHIGS
is open but no archive file is open, it should not cause
any other effect."

cause any other effect."

cause any other effect."
