Actually, an Operand List doesn't have to contain pointers to variables.
It can quite happily contain the variables themselves -- essentially
passing by value rather than by reference.  However, because the general
convention is to pass by reference it is usual to use pointers to pass
the address of the variable.

A few internal IBM programs accept parameters by value and I've had to
build Operand Lists which directly contain variables in order to invoke
them.
