Translator – Operands

Operands are the objects that operators act upon. Basic operands consist of variables, constants and functions with no arguments. More complex operands consist of array elements, functions with arguments, and parenthetical expressions. Technically, the results of operators can be operands to other operators, but this will not be the definition of an operand for the Translator.

Only the basic operands will be added directly to the RPN list. Basic operands are any tokens that are not an operator and do not have a parentheses. I realized that this means that the Internal Function token type needs to be split into Internal Function with and with out parentheses (i.e. IntFuncP and IntFuncN) just like for the one-line define functions (DefFuncN and DefFuncP).

In other words, basic operands are items the don't require arguments. The Translator won't be able to tell the difference between functions with no arguments and variables – both of these will be of the NoParen token type. Therefore, the basic operands are NoParen, Constant, IntFuncN, DefFuncN, ImmCmd (will be the only token on a line), and Remark.
