The following points summarize the use of actions and built-in functions in table references:

•Copy has special cases to allow an entire row to be the source or the destination and to be treated as a series of values, instead of just a single string. For example, you can copy a row to or from a structure.

•You can use references to a row or a column in action statements and built-in functions.

•You cannot pass cell and row references by reference; therefore, they cannot be a parameter to a subroutine. If you want to pass a cell or row to a subroutine, you must copy the cell or row to a variable, then pass that variable to the subroutine, then copy the result back to the table afterwards.

•You can use references to the textual value of an entire row in the same places as string expressions. See the description of the column delimiter is attribute in the table Definition for further information.
