RENAME VARIABLES (old_names=new_names)… .
RENAME VARIABLES
changes the names of variables in the active
dataset. Specify lists of the old variable names and new
variable names, separated by an equals sign (‘=’), within
parentheses. There must be the same number of old and new variable
names. Each old variable is renamed to the corresponding new variable
name. Multiple parenthesized groups of variables may be specified.
When the old and new variable names contain only a single variable name,
the parentheses are optional.
RENAME VARIABLES
takes effect immediately. It does not cause the data
to be read.
RENAME VARIABLES
