Datasetname can be SI, S2,..., or S5. Datasetname must 
include at least two pairs of data points.
DO2VSTATS datasetname:
SETDEPEND Sets datasetname dependent column. Datasetname can 
be S1, S2, …, or S5 and column can be C0–C9.

Storing and retrieving variables in programs
The hp 39gs has both Home variables and Aplet 
variables. Home variables are used for real numbers, 
complex numbers, graphics, lists, and matrices. Home 
variables keep the same values in HOME and in aplets.
Aplet variables are those whose values depend on the 
current aplet. The aplet variables are used in 
programming to emulate the definitions and settings you 
make when working with aplets interactively.
You use the Variable menu ( ) to retrieve either 
Home variables or aplet variables. See “The VARS menu” 
on page 14-4. Not all variables are available in every 
aplet. S1fit–S5fit, for example, are only available in the 
Statistics aplet. Under each variable name is a list of the 
aplets where the variable can be used.
