SAS® Metadata/Dictionary Tables    

Below are a collection of dictionary table SAS® papers.  Along with the DEFINE.XML file to view variable attributes, it may also be useful to create a multi-sheet excel of all datasets and CODEBOOK to characterize data.  

See Pharmaceutical programming section for example of applying variable attributes from an excel file.  See SAS Dictionary Tables Gallery.  See also Proc Contents, Proc FREQ, Excel files, Proc SQL and SAS Macro Programming.  SAS® Savvy Class: Automating Tasks using SAS Macro and Metadata Programming

Dictionary/Array Reference Functions	Result  See SAS Paper, SAS Paper 2
CALL LABEL ROUTINE	Assign label to variable
VLABEL()	Returns the variable's label Example, Y=VLABEL(X); or Y=VARLABEL(X);
VLENGTH()	Returns the length of the string or numeric value from a character or numeric variable
VNAME()	Returns the variable's name, argument is often arrary index reference  See also INDEX("&VAR", 'END') > 0 to compare variable names
VTYPE()	Returns the variable's type (N, C)
VVALUE()	Returns the formatted value
