CONT
Type: Command
Description: Continue Program Execution Command: Resumes execution of a halted program.
Since CONT is a command, it can be assigned to a key or to a custom menu.
Access: !æ ( æis the left-shift of the ‡key).
Input/Output: None
Example: The program
« "Enter A, press { CONT }" { CONT } MENU PROMPT »
displays a prompt message, builds a menu with the CONT command assigned to the first menu
key, and halts the program for data input. After entering data, pressing %CONT% resumes program
execution. (Note that pressing !æ is equivalent to pressing %CONT% .)

CORR
Type: Command
Description: Correlation Command: Returns the correlation coefficient of the independent and dependent data
columns in the current statistics matrix (reserved variable ΣDAT).
The columns are specified by the first two elements in the reserved variable ΣPAR, set by XCOL
and YCOL, respectively. If ΣPAR does not exist, CORR creates it and sets the elements to their
default values (1 and 2).
The correlation is computed with the following formula:
