Functions allow the processing of values or the buildup of control structures.
Is a function unknown, then it is tried to conduct a eva/3 command or macro with the same name. The transfer
value in the function invoking can either be blank or contain a value list.
Example: =testfunction(Values("a", "b", "c")) calls the command or the macro with their names Testfunktion
and delivers the string array with the values a b and c at the invoked macrro or rather at the command.
