Yes i support with srilath By use label option we can give
discriptive names to the particular charcter upto length of
256 character and it is can given either in datastep or
proc step.
Rename is used for changing the name given inthe existing
dataset and it should not exceed 64 charcters and i can be
given only in the datastep.

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.

Even after labeling the variable,we must use old name for
further analysis.
Where as after renaming the variable we must use new name.

Answer / ganesh
Rename takes only 64characters length it can be used either
datastep or proc step and this rename is remains only for
the particular session once u terminate the session rename
options vanishes.
Label takes 256 characters length and its is a global
statment we can specify a brief name and this will remain
for long time untill & unless user delete or cancell the
variable.

Answer / raj
Rename : It is used to rename the existing variable and
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
