Ballard & PGStats, As you have suggested, output in the ODS statement does not need to be surrounded by single quotes. Without the single quotes the new log from ods output Estimates = ratt56(rename=(estimate=adj_pect lower=adj_lcl upper=adj_ucl) keep=estimate lower upper); says: NOTE: The structure of the Estimates table has changed from an earlier release of SAS. WARNING: The variable lower in the DROP, KEEP, or RENAME list has never been referenced. WARNING: The variable upper in the DROP, KEEP, or RENAME list has never been referenced. WARNING: The variable lower in the DROP, KEEP, or RENAME list has never been referenced. WARNING: The variable upper in the DROP, KEEP, or RENAME list has never been referenced. I will need those variables as heading of the columns of the tables to be generated later. Is there any SAS literature on KEEP/DROP within ODS Output? Thanks, Have a great weekend, ArtPsh
