5.9.2 Calling up Objects
Rules
The root of the tree is designated by &.
The branches (levels) of a tree are marked with
a dot (.) when calling up an object.
When calling up an object, it is sufficient to
give only as many letters as necessary to
uniquely assign the object. If the call is not
unequivocal, the first object in the series will be
recognized.
Upper- or lowercase letters may be used.
An object can be assigned a value. Values are
signified at the beginning and end by quotes
("). They may contain up to 24 ASCII charac-
ters.
Numerical values can contain up to 6 digits, a
negative sign, and a decimal point. Numbers
with more than 6 characters are not accepted;
more than 4 decimal places are rounded off.
For numbers <1, it is necessary to enter lead-
ing zeros.
The current object remains until a new object
is called.
New objects can be addressed relative to the
old object:
A preceding dot leads forwards to the next
level in the tree.
More than one preceding dot leads one
level backwards in the tree. n node back-
wards require n+1 preceding dots.
If you must jump back to the root, enter a pre-
ceding &.
