Do Loop, If-Else- conditions in SAS Macros. We have already covered Global and Local Macro variables and Macros along with sample usages in our previous articles. Lets now learn looping and conditional executions in Macros. In general, IF-THEN/ELSE statement, which is part of the SAS macro language, conditionally generates text. then the macro generates the following DATA stepsas - If condition is true then execute a SAS will replace any occurrence of the SAS macro variable qtr with Q1, then Q2, then Q3, etc. Can you see the value in using SAS Macros yet??Copyright 2011 sheepsqueezers.com. Macro Control Structures IF, DO, DO WHILE, etc. If-Then-Else Macro Statement (continued). The IF-THEN-ELSE statement is used to conditionally process statement(s) when certain condition(s) are met.

Macro If Else SAS. From: Internet Comment Copy link April 4.If the conditions that are specified in the IF clause are met, the IF- THEN statement executes a SAS statement for observations that are read from a SAS data set, for records in an external file, or for computed values. Using IF-THEN statements without the ELSE statement causes SAS to evaluate all IF-THEN statements.Subsequent IF-THEN statements are not evaluated. For greater efficiency, you should construct your IF-THEN-ELSE statements with conditions of decreasing probabilities. Beyond IF THEN ELSE: Techniques for Conditional Execution of SAS.Nearly every SAS program includes logic that causes certain code to be executed only when specific conditions are met. This is commonly done using the IFTHENELSE syntax.

To be honest I dont get the question. Creating Macro Variables. In some applications it is desirable to be able to assign macro variable values based on values stored in a SAS data set.What form of the if-then-else structure is sent to. the SAS compiler? Creating Macro Variables. Nearly every SAS program includes logic that causes certain code to be executed only when specific conditions are met. This is commonly done using the IFTHENELSE syntax. In this paper, we will explore various ways to construct conditional SAS logic The following DATA Step is part of a SAS macro. There are two conditions that should be checked when reading the data set returncheck. If the first or second conditions are met, then a macro variable "Datastatus" should take the string value Exclude. Then SAS compiles and executes your program. In general the syntax for a macro is as followsFor this to work we need to use the "if", "then" and "else" statements when evaluating a conditional statement on a macro variable.
