UNION# returns a string containing the union of two (or more) TeLiTab sets
UNION#(Telitab_1$, UnfoldPar_1$, Telitab_2$, UnfoldPar_2$, Mode%)
or
UNION#(Mode%, Telitab_1$, Telitab_2$, ...)
Arguments
...
...
To explain the data:
you have two objects, MODELS and PROJECTS presented as list values in Telitab_1$ containing TeLiTabs themselfs (with several parameters).
LPP is part of the MODELS object (TeLiTab).
When you unfold Telitab_1$ dataset on parameter "LPP", you get:
...
You see that PROJECT still is a separate object (and presented as a list value in Telitab_1$). All other data (which was part of the MODELS object) now is part of Telitab_1$ and thus a table in the TeLiTab.
Telitab_2$ contains the dataset:
...
and UnfolPar_2$ contains "NullString", what means that no unfolding of Telitab_2$ is performed.
...
UNION#(Telitab_1$, "LPP", Telitab_2$, "NullString", 0)
it returns:
0

The UNION# function with Mode%=1 can be used as a database manipulation function. The union of two Telitab sets as produced by this functiun completes a set of data by combining data from two source sets in a single table (see also SECTION#() ).
