When you unfold Telitab_1$ dataset on parameter "LPP", you get:
1
"PROJECTS"
{
1
"CLIENT$" "YardX"
}
0
-4 "1" "2" "3" "4"
"MODMAT$" "wood" "foam" "wood" "plywood"
"LPP" 112.30 133.80 98.60 145.00
"B" 17.80 21.50 16.42 22.40
"T" 7.65 9.20 6.70 9.40
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:
0
-4 "1" "2" "3" "4"
"MODNO$" 5684 6231 6301 6537
"LPP" 112.30 162.70 133.80 118.50
"B" 17.80 27.80 21.50 16.70
"T" 7.65 11.20 9.20 6.80
and UnfolPar_2$ contains "NullString", what means that no unfolding of Telitab_2$ is performed.
...
UNION#(Telitab_1$, "LPP", Telitab_2$, "NullString", 0)
it returns:
0

Please note that the union simply contains the sum of two Telitab sets and contains the combined parameters and cases of both sets (Mode%=0). Cases 4-8 have empty object values for PROJECTS.

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$.
