Name Description
NOT Logical NOT. Returns NOT(x).
OCTM Select Octal mode
OFF
Turn the calculator off (programmable). (Pressing ■OFF does not execute the
programmable OFF function.)
OLD Recall the current element from the indexed matrix. (Equivalent to RCLEL.)
ON Continuous on. Prevent the calculator from automatically turning off after ten minutes
of inactivity.
OR Logical OR. Returns x OR y.
PERM Permutations of y items taken x at a time. Returns y!/(y – x)!
PGMINT Select a program to integrate. Parameter: global label (indirect allowed)
PGMSLV Select a program to solve. Parameter: global label (indirect allowed) ,
PI Put an approximation of π into the x-register (3.14159265359).
PIXEL Turn on a single pixel (dot) in the display. The location of the pixel is given by the
numbers in the x- and y-registers.
POLAR Select polar coordinate mode for displaying complex numbers.
POSA Position in Alpha. Searches the Alpha register for the target specified in the x-register.
If found, returns the character position; if not found, returns -1.
PRA Print Alpha register.
PRLCD Print LCD (liquid crystal display). Prints the entire display.
PROFF Printing off. Clears flags 21 and 55.
PROMPT Display the Alpha register and halt program execution.
PRON Printing on. Sets flags 21 and 55.
PRP Print program. If a label is not specified, print the current program. (Not
programmable.) Parameter: global label (optional)
PRSTK Print stack. Print the contents of the stack registers (x, y, z and t).
PRUSR Print user variables and programs.
PRV Print variable. Parameter: variable name (indirect allowed)
PRX Print x-register.
PRZ Print statistics. Prints the contents of the summation registers.
PSE Pause program execution for about 1 second.
PUTM Put matrix. Stores the matrix in the X-register into the indexed matrix beginning at the
current element.
PWRF Select the power curve-fitting model.
QUIET Toggle flag 26 to disable or enable the beeper (Not programmable )
RAD Select Radians angular mode
RAN Returns a random number (0 ≤ x < 1)
RCL Recall data into the x-register. Parameter: register or variable (indirect allowed)
RCL+ Recall addition. Recall data and add it to the contents of the x-register. Parameter:
register or variable (indirect allowed)
RCL- Recall subtraction. Recall data and subtract it from the contents of the x-register.
Parameter: register or variable (indirect allowed)
RCL× Recall multiplication. Recall data and multiply it by the contents of the x-register.
Parameter: register or variable (indirect allowed)
RCL÷ Recall division. Recall data and divide it into the contents of the x-register. Parameter:
register or variable (indirect allowed)
RCLEL Recall element. Recalls the current matrix element from the indexed matrix.
RCLIJ Recall the row- and column-pointer values (I and J) for the indexed matrix.
RDX, Select a comma to be used as the radix mark (decimal point).
RDX. Select a period to be used as the radix mark (decimal point).
REALRES Real-results. Disables the calculator's ability to return a complex result using real-
number inputs.
REAL? If the x-register contains a real number, execute the next program line; if the x-register
does not contain a real number, skip the next program line.
RECT Select Rectangular coordinate mode for displaying complex numbers.
