4.4.10 How to use object parameters

All parameters can be accessed with the expression element.parameter followed by the name of the required parameter, e.g.:

element.parameter.gs_list_manufacturer

Note that it not necessary to enclose the parameter name in quote marks or parentheses. The resulting value is void if the element either doesn’t have parameters or doesn’t have a parameter with the requested name – this does not cause errors and any calculations using that value will yield a result of zero.

If the parameter is an array, only the first value of the array is returned. Quantities is highly tolerant of parameter value type differences as noted in section 4.4.2, Does the data type matter?.
