there are no other variables beginning with var, you can use the colon-operator, which acts as a wildcard, e.g. SAS Macro Variable Name Value dsn Table 4. But just keep in mind that the remaining 4 execution time macro quoting functions - %NRQUOTE(), %BQUOTE(), %NRBQUOTE() and %SUPERQ() - will work too. a character expression that produces a macro variable name. Example 7: Using a Macro to Create New Variable Names from Variable Values Tree level 3. Use SAS macro variable to create variable name in PROC SQL. This form is useful for creating a series of macro variables. But this macro does generate SAS code which assigns a value to the macro variable specified as the second argument (result=NOBS). Variable name. If you want commas between the variable names, all you have to do is change the 'separated by' value from ' ' to ', '. Variable names are just that: they are a name used to refer to a variable in a dataset. ALERT - The process of updating a lookup table in SAS® Business Rules Manager (running in UNIX operating environments) does not work properly: F5B004: 66092: SAS® Business Rules Manager 3.3 does not display an equal sign for a rule when the software is installed as an upgrade: F5B005 When a start position and length are specified, then this function is used for abstracting character string. Here it is:

In particular, an empty argument position will not generate a NULL argument, but a zero length argument. We discussed SAS Data Set in our last tutorial, now we will be discussing SAS Variable, properties of SAS Variable, SAS Variable types and how we can create variables in SAS. Note: The arguments to %SYSCALL are evaluated according to the rules of the SAS macro language. Note: This form is most useful when macro-variable is also the name of a SAS variable or a character expression that contains a SAS variable because a unique macro variable name and value can be created from each observation, as shown … Moreover, we will see some examples of Variables in SAS Programming Language. SAS Semicolon In MAcro variable. NOTE: The syntax of the %SUPERQ() function is quite different from the rest of the pack. No macro variable can begin with begin with SYS. DSNAME is the name of the macro variable. For example: " if p_adj >= 0.025 and p<0.05 then decile_ =1;" – B_Miner Dec 23 '14 at 1:16. CALL SYMPUT does not have the power to create a local symbol table. The following are the rules for creating a macro variable: SAS macro variable names can be up to 32 characters in length. When naming a variable in SAS, there are a few rules you must follow: The name cannot contain more than 32 characters. 1. I know this doesn't answer your question, but this generally isn't a good way to do recoding/binning. optimization,sas. The suffix variable counts the observation(_n_) and appends count onto the macro variable Fname so that unique Macro variables are created for each name. For example, the CALL SYMPUT statement builds a series of macro variable names by combining the character string POS and the left-aligned value of _N_ and assigns values to the macro variables POS1, POS2, and POS3. The use of the upcase function in the where statement avoids problems with someone passing the dataset name in the wrong case. The content of macro variable can be up to 32K (in version 7, the limit is 64K). SAS drop multiple variables indexed by tens. These courses are part of our SAS Programming curriculum. Ask Question Asked 5 years, 4 months ago. Subsequent characters can be letters, numeric digits, or underscores. I'm trying to create a set of flags based off of a column of character strings in a data set.
