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. Calling up the dialog language
&Config.Aux.Language or &C.A.L
Upper- or lowercase letters may be used. &C.A.L or &c.a.l
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. Entering the dialog language:
&C.A.L"english"

"0.1"
incorrect entry of numbers
"1,5" or "+3" or ".1"
The current object remains until a new object
is called. entry of another dialog language:
"deutsch"
New objects can be addressed relative to the
old object:
A preceding dot leads forwards to the next
level in the tree. From the root to node 'Aux': &C.A
Forward from node 'Aux' to 'Prog': .P
More than one preceding dot leads one
level backwards in the tree. n node back-
wards require n+1 preceding dots. Jump from node 'Prog' to node 'Aux' and select
a new object 'Language' at this level: ..L
If you must jump back to the root, enter a pre-
ceding &.
Change from node 'Language' via the root to
node 'Mode': &M
