PROGRAMMING KEYS (USE IN THE PGM MODE ONLY)
[ 2ndF ] [ PGM ]─Program Mode Set and Clear Key
Set the calculator to the learn program mode. PGM appears on the
display and the previous contents of program memory are cleared.
When you finish entering the program, press [ 2ndF ] [ PGM ]. The
program you just entered is stored in the program memory. PGM
disappears and the calculator exits the program mode.
[ RUN ]─Compute Key
Runs the recorded program.
[ 2ndF ] [ [X] ]─Specify Variable Key
Lets you have the calculator wait for an entry during a program.
[ 2ndF ] [ HALT ]─Temporarily Halt Calculation Key
Temporarily halts a program so you can view the intermediate results
or interrupt calculation.
STATISTICAL KEYS (USE IN THE STAT MODE ONLY)
[ 2ndF ] [ STAT ] Statistical Mode Select Key
Sets the calculator to statistical calculation mode. STAT appears in the
display.
[ 2ndF ] [ CAD ] Statistical Register Clear Key
Clears the statistical calculation registers.
