Grouping Variables
Grouping allows you to make a copy of two or more variables residing in
RAM and then store them as a group in user data archive. The variables
in RAM are not erased. The variables must exist in RAM before they can
be grouped. In other words, archived data cannot be included in a group.
To create a group of variables:
1. Press y L to display the
MEMORY
menu.
2. Select 8:Group... to display
GROUP UNGROUP
menu.
