After conversion of Excel files to SAS data sets using the %XLXP2SAS macro the VNAME function was applied to extract relevant data from variable names.

Xia Ke Shan, iFRE Inc., Beijing, China; Kurt Bremser, Allianz Technology Austria See full list on blogs.sas.com If you use RENAME= on an input data set that is used in a SAS procedure, SAS changes the name of the variable in that procedure. The list of variables to rename must be enclosed in parentheses: proc print data=test(rename=(score1=score2)); Oct 29, 2020 · Although SAS is able to open the file, if the file is not a text file with embedded text attribute bytes, then the data appears as random normal text characters with random colors and highlighting. If you choose to stop opening the file, SAS returns to the FNAME window. To confirm that we've read the files into SAS, we can view one of the resulting SAS data sets in the SAS Studio Output Data Viewer. At this point, the macro variables &Name1 etc. can be parsed with %scan() to obtain the name of the file and used to write output files once they have been further manipulated via a DATA step. May 22, 2020 · A frequent question in the SAS Community is to search for a value in an array or list of variables.

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: Mar 28, 2016 · 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. specifies any SAS character variable.

Either numeric or character. This post demonstrates a few different approaches to the problem. The are iterating through the array manually, using the Whichn/Whichc Function and the SAS In Operator. New to SAS 9.1, the function VVALUEX uses the literal name of a variable to return the formatted value of the variable in a data STEP (Schreier, 2004). The VNAME function returns the name of a variable referenced in an array (Ye & Lin, 2000), so the following section use VVALUEX and VNAME in a data STEP output the unexpected fileref is any SAS name when you are assigning a new fileref.

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. Base SAS Procedures CALL VNAME Routine Tree level 5. Node 99 of 703. CALL VNEXT Routine VNAME returns the name of the specified variable.

At this point, the macro variables &Name1 etc. can be parsed with %scan() to obtain the name of the file and used to write output files once they have been further manipulated via a DATA step.

prints the first two letters of the day name. var name sex age;. run;. Here is the resulting output: Notice that, by default, SAS adds a variable OBS in the output for proc print that indexes the rows in the data SAS reserves a few names for automatic variables and variable lists, SAS data This allows SAS to associated a name with the stored data so you can easily SAS Institute (or SAS, pronounced "sass") is an American multinational developer of analytics statistical analysis system (hence the proper name, Statistical Analysis System) that was originally used primarily by agricultura Name, Sex, Age Which of the following files is a permanent SAS file? In a DATA step, how can you reference a temporary SAS data set named Forecast?

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:

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 Table of Contents; Topics; Loading VARNAME Function Returns the name of a SAS data set variable.

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.

Posted 03-27-2019 04:29 PM (1003 views) I'm writing a user-written Sample data is attached: How to create a dataset that contains the variable as value ,its origibal value and truncated values as shown below: In the first record, business_name is truncated for company name "Byrum". The lengths of business_name and new_business_names are different and their values (You can prove this with the SAS RTRACE system option.) I am of the opinion that a sql query to dictionary.columns is the fastest of the methods outlined here. Obviously the macrotised code would work without the macro but the point of the macro here is I think as a utility; put the code into your favourite macro library and you never need to VNAME does not accept an expression as an argument.

Otherwise, the function returns a blank. SAS Analytics 15.2 Tree level 1. Node 5 of 31. Base SAS Procedures CALL VNAME Routine Tree level 5.
