CALL SYMPUT and CALL SYMPUTXCALL SYMPUT and CALL SYMPUTX in SAS are the most commonly used DATA Step call routines to interact with the Macro Facility in SAS. Both are used to assign a value of DATA step to a macro variable.In this article, I will demonstrate some of the uses and important facts of […]Continue reading
EVAL and SYSEVALF are the two macro functions that evaluate arithmetic expressions and logical expressions. %EVAL The %EVAL function is used to evaluate integer arithmetic or logical expressions. The argument passed in the %EVAL function is converted from character to numeric and the results are converted back to character. All parts of the macro language […]Continue reading
SAS Macro quoting functions are used to resolve these ambiguities by masking the significance of special characters so that the macro processor does not misinterpret them.Continue reading
Macro variables in SAS are used extensively for reusing codes. You can create a multi-usable program in which analysis of variables can be controlled by updating the values of macro variables.
SAS provides an elegant solution to overcome these problems with the CALL SET routine. You can convert data step variables into macro variables with a few lines of code using the %SYSCALL SET routine. This routine also allows you to convert and process one observation of data step variables at a time thus saving memory usage.
