Simple Statistics Program - need to chance

[David Hayden]

You could use the numeric input flag (22). Something like:

Code:

LBL 00
TONE 5
"ENTER DATA"
CF 22
PROMPT
PRX
FC? 22       // If input was entered, F22 will be set
GTO 01
"SIGMA +" --------> key "A"
GTO 00

Also, at the bottom of the program you could replace

Code:

FS? 55
RTN
STOP
RTN
.END.

with

Code:

FC? 55
STOP
.END.
