function TT_EvalTags_CielovyObjekt() { return 'Example:
\ If a constant expression of value 1 is defined, the process D2000 Calc (admistrator of \ objects of Eval tag) type ) ensures that all fields of a defined column will \ have the same value of 1.

\ If there is an expression Sec+1, the process D2000 Calc (admistrator of \ objects of Eval tag) type ) ensures that all fields of a defined column will \ have the same value, which corresponds to the value of system variable \ Sec increased by 1.

\ A reasonable use of this option is the possibility to use a reference to a column of a structured variable\ in an expression, where in brackets (row index) is a value of 0. Such reference will be reffered to as \ a reference to a column of a structured variable. This ensures that when evaluating an expression, the \ value of which is inserted into e.g. 3rd row, all the indeces with the constant value of 0 will be \ replaced with the value of 3.

\ \ Example:
Structured variable SV.Production consists of 10 rows and 3 columns.

\   Column        \ Type           Meaning
\ Products                 Int\                Number of products
\ Rejects                 \  Int \                Number of rejects
\ ProductsOK            Int \                Number of good-quality \ products

\ Obviously the following equation can be formed:
\ ProductsOK = ProductsALL - Rejects

\ Provided that the columns ProductsALL and Rejects are populated fully automatically \ and the value of the column ProductsOK is to be determined, it can be done with the configuration of \ an eval tag as described below:
\ Expression:
\ SV.Production[0]^ProductsALL - SV.Production[0]^Rejects

\ Calculation of the difference will be in the column SV.Production[0]^ProductsOK.
\ Note: The expression may contain references to columns of other structured variables.'; }
