1. Label is global and rename is local i.e., label statement
can be used either in proc or datastep where as rename
should be used only in datastep.

2.If we rename a variable, old name will be lost but if we
label a variable its short name(old name) exists along with
it's descriptive name.

further analysis.

permanent. Mainly it is used in merge and set statement if
same column name is available in the datasets being merged
or set.

label : It is only for displaying purpose for better
readability.

Answer / salma begum

Rename:
It is used to change the name of the VARIABLE peremanently.
Renaming should be done in a standardized was (start with _ or letter, should not start with special charaters or numbers).

Label:
It temporarily changes the variable name.
it can be written in data step or proc step.
Labelling can be done in unstandardized way (can contain blanks, start with numbers or letters or _) .
Label will not change the actual name of the variable
