Passing arrays – PB Docs 2019

When an argument is an array, you specify brackets as part of the
argument name in the declaration for the function or event.

Variable-size array as an
argument

For example, suppose a function named uf_convertarray accepts a
variable-size array of integers. If the argument’s name is intarray,
then for Name enter intarray[ ] and for Type enter integer.

In the script that calls the function, you either declare an array
variable or use an instance variable or value that has been passed to
you. The declaration of that variable, wherever it is, looks like
this:

When you call the function, omit the brackets, because you are
passing the whole array. If you specified brackets, you would be passing
one value from the array:

Fixed-size array as an
argument

For comparison, suppose the uf_convertarray function accepts a
fixed-size array of integers of 10 elements instead. If the argument’s
name is intarray, then for Name enter intarray[10], and for Type enter
integer.

The declaration of the variable to be passed looks like
this:

You call the function the same way, without brackets:
