• Telitab$ ia a string expression containing a Telitab set.
• Object is an object containing a datas etdataset
• UnfoldPar$ is a name of parameter for which to unfold a dataset.
• UnfoldPar$ can be specifically for a parameter in a particular object of the solution, for example "SPEEDPOWER.Vs_kts". In that case, the data will be unfolded on the level of Vs_kts in the SPEEDPOWER object. This definition is expecially required when Vs_kts is available in serveral object of the solution you want to use and you specifically want to unfold at the position of SPEEDPOWER.
• If UnfoldPar$ = "NullString", no unfolding of Telitab$ is performed. This basically is a selection, a query without any query arguments, except for the Mode% and InpVar variables.
• Mode% is the filter option of the UNFOLD#() function:
• For Mode%=0, the function returns the unfolded Telitab without a subset of parameters provided in the optional list InpVar;
• For Mode%=1, the function returns the unfolded Telitab with only a subset of parameters provided in the optional list InpVar
• InpVar can contain actual parameters Par1,..,Parn or the names "Par1",..,"Parn". In the first option, Par1 to Parn need to be present in the knowledge base AND in the current solution. With "Par1",..,"Parn", the parameters are only expected in the Telitab set. "Par1",..,"Parn" is most convenient.

If Telitab_1$ contains the dataset:

2 
"MODELS" 
{ 
0 
-4 "1" "2" "3" "4" 
"MODMAT$" "wood" "foam" "wood" "plywood" 
"LPP" 112.30 133.80 97.60 145.00 
"B" 17.80 21.50 16.42 22.40 
"T" 7.65 9.20 6.70 9.40 
} 
"PROJECTS" 
{ 
1 
"CLIENT$" "YardX" 
}

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).

...

which unfolds Teltab$ for parameter "LPP" returns:

1 
"PROJECTS" 
{ 
1 
"CLIENT$" "YardX" 
} 
-4 "1" "2" "3" "4" 
"MODMAT$" "wood" "foam" "wood" "plywood" 
"LPP" 112.30 133.80 97.60 145.00 
"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.

...

UNFOLD#(Telitab$, "LPP", 0, "MODMAT$", "PROJECTS")

returns:

0 
3 "LPP" "B" "T" 
"1" 112.30 17.80 7.65 
"2" 133.80 21.50 9.20 
"3" Â 98.60 16.42 6.70 
"4" 145.00 22.40 9.40

Parameters MODMAT$ and object PROJECTS are removed.

...

UNFOLD#(Telitab$, "LPP", 1, "MODMAT$", "PROJECTS")

returns:

1 
"PROJECTS" 
{ 
1 
"CLIENT$" "YardX" 
} 
1 "MODMAT$" 
"1" "wood" 
"2" "foam" 
"3" "wood" 
"4" "plywood"

Parameters MODMAT$ and object PROJECTS are the only ones presented.
