UNION# returns a string containing the union of two (or more) TeLiTab sets

Syntax

UNION#(Telitab_1$, UnfoldPar_1$, Telitab_2$, UnfoldPar_2$, Mode%)

or

UNION#(Mode%, Telitab_1$, Telitab_2$, ...)

...

To carry out the unfolding and the UNION we write: 

UNION#(Telitab_1$, "LPP", Telitab_2$, "NullString", 0)

...

If the union should combine the parameter values of the cases with the same value of the overlapping parameters Mode%=1 should be used:

UNION#(Telitab_1$, "LPP", Telitab_2$, "NullString", 1)

...

Case 1 and 2 of the result are cases 3 and 4 from the unfolded object MODELS in Telitab_1$. 
Case 3 is a combination of of the cases 1 of both input sets. 
Case 4 corresponds with case 2 from Telitab_2$. 
Case 5 is again a combination of respectively the cases 2 and 3. 
Case 6 corresponds with Case 4 from Telitab_2$.

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#() ).
