PROGRAM 4: Deletion of multiple structures
CHARACTERISTICS: nnnn
OPERATOR SCRIPT: passive test
DESIGN:
Use <open structure> and <execute structure> to set up the CSS
as follows:
100
/ \
1/ \2
/ \
103 104 102
/ \ \ / \
1/ \2 1\ 1/ \2
/ \ \ / \
105 105 106 109
/ \ / \
1/ \2 1/ \2
/ \ / \
107 108 110
The nodes of the graph (100 and above) represent structures, and the
labelled edges are references to invoke (lower) structures. The
labels (0-2) represent the element position of the <execute structure>
function within the calling structure.
TEST: #SR 1 2
"Changes to the CSS should be reflected when deleting more than
one structure."
delstr = 103
<delete structure> delstr
examine the contents of the CSS for the existing structure identifiers
and the associated element references
if (CSS contents <>
105, 100
| |
0| 1|
| |
104 102
\ / \
1\ 1/ \2
\ / \
106 109
/ \ / \
1/ \2 1/ \2
/ \ / \
107 108 110 ) then
goto fail_test

delstr = 106
<delete structure> delstr
examine the contents of the CSS for the existing structure identifiers
and the associated element references
