Hello,   I'm trying to do a validity check on table A by checking to see if the data matches values that are determined in table B. The table (B) has two columns, the variable name and values in a long form:  datalines; Client_Type 1 Client_Type 2 Client_Type 3 Client_Vendor 1 Client_Vendor 2 Client_Vendor 3 ; What is a good way to check that the same variable will conform to those values in table B? Since there are 200 variables, is there a way to create a macro to do this more efficiently?    Thanks in advance for your time! ... View more
