Although they appear identical on the stack, there are two important

differences between formal variable names (that have no associated

objects) and quoted variable names (that have associated objects):

■ Evaluating a formal variable doesn't appear to do anything, because

the formal variable is returned again to the stack. Evaluating the

quoted name of a variable containing an object evaluates that

object.

m Formal variables never appear in the VAR menu. All variables that

appear in the VAR menu have an associated object. However, you

ran store a formal variable name in a, VAR variable with a difftreni

name.

Sxaiiiple: Enter the name

onto the stack using single-quotes.

1: 'RDD£'

Example: Enter the formal variable name, C, onto the stack by

using the unquoted name. If an actual variable, C exists

somewhere in the current path, you wdll see its contents

instead of the variable name.
