Rules Example
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 neces-
sary 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
&C
onfig.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. Val-
ues are signified at the beginning and
end by quotes ("). They may contain up
to 24 ASCII characters.
Numerical values can contain up to 6
digits, a negative sign, and a decimal
point. Numbers with more than 6 char-
acters are not accepted; more than 4
decimal places are rounded off. For
numbers <1, it is necessary to enter
leading zeros.
Entering the dialog language:
&C.A.L"english"
correct entry of numbers:
"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
backwards 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
preceding &.
Change from node 'Language' via the
root to node 'Mode': &M
