Using Functions SYSFUNC and IFC to Conditionally Execute Statements in Open Code

This paper explains how to conditionally execute statements in open code without having to wrap the code in a macro. This is accomplished by combining the macro function sysfunc with the data step function ifc. The result is that parameterized include programs gain the power of conditional processing — %if ... %then — for which macros are usually used. This is another in the Journeymen’s Tools series.
