PROGRAM 2: Deletion of a structure network with the reference
flag set to delete and references are made to the
closed specified structure
CHARACTERISTICS: nnnn
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
| |
|2 |1
| |
| |
| 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.
TEST: #SR 3 4
"When the reference handling flag is set to delete and
the closed specified structure is referenced outside the
structure network the following changes should occur to
the CSS:
All closed structures contained in a structure network
are removed."
specf = 106
reffg = DELETE
<delete structure network> using specf, reffg
pass/fail depending on (CSS contents =
