PROGRAM 5: Deletion of a structure network with the reference flag
set to delete and references are not made to the
open specified structure
CHARACTERISTICS: ynnn
OPERATOR SCRIPT: passive test
DESIGN:
Use <open structure> and <execute structure> to set up the CSS
as follows:
100
/ \
/ \
1/ \2
/ \
/ \
101 102 120 130 140
| | / | \ | /| |
1| |2 / | \ | / | 1|
| | 1/ 2| 3\ 1| /1 |2 |
| | / | \ | / | |
103 / | \ |/ | 142
104 105 106 107
| | | | / /\
1| |2 /|\ | / / \
| | 1/ | \3 1| 1/ /2 \3
109 / | \ | / / \
/ | \ |/ / 113
110 | 108
| |
| |1
|2 |
| |
| 111
| / |
| 1/ |
| / 2|
|/ |
114 115
The nodes of the graph (100 and above) represent structures, and the
labelled edges are references to invoke (lower) structures. The
labels (1-3) represent the element position of the <execute structure>
function within the calling structure.

"When the reference handling flag is set to delete
and the open specified structure is not referenced
outside the structure network the following changes
should occur to the CSS:
All closed structures contained in a structure network
are removed.
The specified structure is OPEN and EMPTY."
specf = 120
reffg = DELETE
<open structure> specf
<post structure> specf
<delete structure network> using specf, reffg
pass/fail depending on (CSS contents =

"<Delete structure network> with the reference flag set to
delete and an open specified structure which is not referenced
outside the structure network should cause that structure to
exist in the CSS as an open structure."
use <inquire open structure> to determine
stype = the structure status open or close
strref = structure id
if (stype = OPEN and
specf = strref) then
pass
<close structure>
else
fail
endif
TEST: #SR 1
"<Delete structure network> with the reference flag set to
delete and an open specified structure which is not referenced
outside the structure network should cause that structure
to exist in the CSS as an empty structure."
use <inquire structure status> on the specified structure to determine
strsti = structure status identifier
pass/fail depending on (strsti = EMPTY)
TEST: #SR 10
"<Delete structure network> should cause the open specified structure
not referenced outside the structure network to become unposted from
the workstation when the reference handling flag is set to delete."
Use inquire posted structures to determine:
pstnum = number of posted structures
<inquire posted structures> pstnum
pass/fail depending on (pstnum = 0)
