Optional parameters are values passed to SUB and FUNCTION procedures. They are always enclosed in parenthesis inside the procedures.

SUB SubName[(parameter [[[AS]] Type][, ...])]

FUNCTION FunctionName[(parameter [[[AS]] Type][, ...])]

CALL SubName[(parameter[, ...])]

SubName [parameter][, ...]

FunctionName[(parameter[, ...])]

Usage:

Inside of sub-procedures, multiple parameters variables are separated by commas in a list and always enclosed inside of parenthesis.
When CALL is used to call a SUB procedure all parameters must be enclosed inside parenthesis too.
When just the procedure name is used to call a SUB, the parameters are listed after the name. Multiple parameters require commas.
FUNCTION procedure parameters are always enclosed in parenthesis. Multiple parameters are separated by commas.
Parameters can be literal values or variables when a SUB procedure is called or a FUNCTION procedure is referenced.
To pass parameter variables by value to protect the value in a call, parenthesis can be placed around each variable name also.
To pass arrays to a sub-procedure use empty brackets after the name or indicate the index in the call.
