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 |
|
|
Returns the variable's label Example, Y=VLABEL(X); or Y=VARLABEL(X); |
|
|
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 |
