Quite often it is necessary to set a default value for a macro parameter that is passed to a program. If the program is a macro, the %IF statement can be used to check if the value is provided and provide a default value if not. Since %IF statements are not allowed outside of macros, that technique won't work for a non-macro program (e.g., a file/program that is %INCLUDEd). The following code snippet demonstrates the use of the COALESCEC function to assign a default value.
%global myParameter; /* ensure it exists */ %let myParameter = %sysfunc(coalescec(&myParameter,default-value));
