Macro is not a replacement for Base SAS programming, it is just a find/replace mechanism. So try the below code. how could I delete all macro variables defined by user during program execution. By default, the macro variable will be padded with blanks (per the width of the format). I used the automatic variable _n_ to avoid duplicating variable names. You can also evaluate By default, VMACRO is a data view where SAS automatically maintains tokens assigned to macro variables during the SAS session. The values are wrapped onto multiple observations when they exceed 200 characters. This needs to be surrounded by quote, because otherwise R would try to assign the contents of sales. The macro is explained here, it's pretty simple. To be fair, that is a mess of code and you may have other problems in there. data _null_; set summaryOut; %let meanY=%SYSFUNC(meanY); % Use PROC CONTENTS and output to dataset. 2. Rule #1 for using macro language: start with working code without any macro use. I want to build a macro that does the following data steps, but I am not sure how to use the consecutive variable list. Like macro variables, you generally use macros to generate text. You have a couple of problems with the definition and use of your macro variables: The macro variable V3 does not get resolved when put in single quotes ('&V3'), use double quotes: "&V3". Hello, I have what I thought was a simple macro using SYMPUTX to assign the number of observations of a dataset to a macro variable. 1 Like 3 REPLIES 3.

Once you pick one of those for the source of the variable list then the easiest way to generate a DROP statement like that is to put the variable names into a macro variable using PROC SQL. It is providing mean of first variable only but I want mean of all the variable and group by with names. macro'; data _nu Hi all! I am trying to create a macro to dynamically compute cumulative returns across variables in my dataset. 11 Likes 4 REPLIES 4. I tried using :into clause and it is giving me just the first row value but if i use separated by ',' it works fine. But In general, while the macro variable is created it does'nt store leading or trailing space in it . In general you don't want to move data into macro variables (which are text) and then back into data. For example, the following statements write the following result: %let a=first; %let b=macro variable; %put &a ***&b***; proc sql; select * from dictionary. Tom. I call eg. The values are: you can then use the macro variable in a SAS statement: Var = put(Var,&Format); Without the dot as suffix you have to use TWO periods after the macro variable reference. I have a macrovariable that contains quotes and ampersand (I need it for the excel file). ; run; You can create macro variables inside a data step using CALL SYMPUTX, and then after assigning the value of the country name to the maacro variable, you can run your macro %dostuff. Creates the same macro variable over and over. To most quickly locate any macro variable, I prefer the view to list names in order. secure. I am sure that the probolem is the date does not have single quotes. But to answer your question: Each iteration for resolving the macro variable will consume one dot. In data step Macro variables created in a macro will be local to that macro, unless they already exist in the global symbol table. Specifically, %macro prog (infile, output, p1, p2, o1, o2) in the above macro, I would like to input infile name, output name, parameter 1 and 2 (p1 and p2), and with two optional parameters o1 and o2. So you should first create the proper SQL code for the IN operator. This is one of the reasons i highly recommend you use Base SAS programming for data manipulation, and leave macro requirements out of it. Since these lists can get really long, I sometimes have to create 10, 20, even 40 lists to contain all the strings. vmacro view and adapt the following program to your Learn how use the CAT functions in SAS to join values from multiple variables into a single value. Saurabh13. Mark as New; Bookmark; It seems to me that macro variables (or macros) are not needed here. The problem I'm having is how to pass the Rule of thumb: moving data into macro-variables is a bad idea in almost all cases i can think of, because when creating a lot of variables, or one variable containing a list of values, you will have to write loops to process the information.

You can assign large or small amounts of text to macro Sorry if I had missed it, but will you touch on Macro Variables scope? Your sample macro programs keep using Global macro variables! Macro variable scope is a complex topic Although the examples in this section show macro variable references in a FOOTNOTE statement, macro variables can be referenced anywhere that the information they supply is The macro variables are available to the SGRENDER step when the macro executes. 0 Likes 10 REPLIES 10. Just use the macro variables to generate the code needed to set your dataset variables. You can also use Use the Symget Function in the Data Step to retrieve the value of the macro variable during DATA step execution (not when it compiles). 1 Programmers have defined a bunch of global macro variables. There are also variables created from a different macro calle Be sure to save your user-defined %FORMAT function in your stored compiled macro or autocall library for convenient re-use!
