You can edit a function call in that way, that also the
parameter names are contained, not only the parameter
values. But nevertheless the position (sequence) of the
parameters must be the same as in the function definition.
Make sure that the areas for the selectors which are used in
the CASE instruction, don’t overlap.
A CASE instruction may not contain more than one ‚ELSE'
instruction.
Make sure that the input for the jump respectively the
