WHAT IS VNAME? SAS has several functions that will return information about a variable. The V NAME function is used in the DATA step and will return the variable name. The default length of the returned value is 200 characters. Use the VNAME function when the variable name is the data we are interested in obtaining instead of the value of the variable.
Node 3 of 703. VNAME returns the name of the specified variable. VNAMEX, however, evaluates the argument to determine a variable name. If the name is a known variable name, the function returns that name.

the name is a known variable name, the function returns that name. Otherwise, the function returns a blank. SAS Analytics 15.2 Tree level 1. Node 5 of 31.
Variables and their names are created by SAS during the compilation phase of the data step. The VNAME function works during the execution phase, when variables have already been defined, and when additional variables cannot be defined. So what you are looking for is quite probably a macro solution:
Otherwise, the function returns a blank. SAS® Viya® Programming Documentation Table of Contents; Topics; Loading I learned about the VNAME function from Ron Cody's book "SAS Functions by Example" and the excellent SAS training course of the same name. First, we need to know how many flag variables there are so we can properly dimension a temporary array which will hold the values extracted from the variable names. If you need to access the variables names of a sas dataset, vname( ) combined with the array statement will be useful.

SAS has pre-defined formats for certain types of variables like dates and allows users to create their own formats for specific situations. Earlier we saw some examples of pre-defined formats when we covered date functions.
SAS has pre-defined formats for certain types of variables like dates and allows users to create their own formats for specific situations. Earlier we saw some examples of pre-defined formats when we covered date functions. Here, we will focus on how to create and apply user-defined formats. SAS returns 0 if the operation was successful, and a value other than 0 if the operation was not successful.
Viewed 577 times 2. I have a database where 12,000 variables are named SAS stores information about datasets in dictionary tables, which have views available in the sashelp library. Take a look in some of the sashelp.v* tables to see what kind of information is available. The proc sql colon is used to store values in a macro variable, which can then be used in the rename statement. SAS user and SAS help: Both are the permanent storage place for SAS files, But in SAS user only. user specified files are available , but in SAS help users specified file and system (SAS) specified files are also available. File: This concept is used to create a shortcut for external files from outside of SAS environment to SAS environment.
If you need to access the variables names of a sas dataset, vname( ) combined with the array statement will be useful. Example (Features: vname(), array, _character_) The raw dataset has 10 variables: var0 var3 var6 var9 var12 var18 var24 var36 var48 number, where the previous 9 variables are binary (Yes/NO) variables and the number… VNAME function Posted 11-28-2007 09:57 AM (527 views) Any suggestions where to get more information about VNAME function You can just see an example in the SAS Using CALL VNAME The most obvious method of creating a "variable name" data set is to use the CALL VNAME routine. Like other SAS routines, CALL VNAME is used within a data step and has the following form: CALL VNAME(variable 1, variable2): Where VARIABLE 1 is the name of a variable from a source data set in which a SAS Communities Library / vname to the rescue; Bookmark Subscribe. vname to the rescue.
