RPL>
Type: Command
Description: User RPL program function. This function allows for the entry and execution of User RPL
programs while in algebraic mode. While RPL programs can be written in algebraic mode
without the use of this function, some RPL constructs, such as FOR…NEXT loops, will
produce an error message if not preceded by the RPL> function. As an algebraic function, it will
be placed on the command line with a pair of parentheses attached, which must be removed
before its use.
For example, to enter the user RPL program of
<< 1 5 + >> in algebraic mode, choose the
RPL> function from the catalog and press
`. Remove the parentheses by pressing ™ƒƒ.
Then enter the program by pressing
…å1#5#+`. The program object will
now be on the first command line. It can be evaluated by pressing
N!î`.
