如何在宏语言的%if语句中使用in逻辑语句【转载】

    This example turns on the MINOPERATOR system option to make the IN operator available.  The MINDELIMITER= %MACRO statement option to change the delimiter from a space to a comma.  The MLOGIC system option is also turned on to show how the %IF condition is evaluated.

 

options minoperator mlogic;
%macro test(value)/mindelimiter=',';

%if &value in 1,2,3,4,5,6 %then
  %put Value found within list.;
%else %put Value not in list.;

%mend;

%test(3)


/*Prior to SAS9.2, the following syntax was used*/
%macro test(value);
  %if &value=1 or &value=2 or &value=3 or &value=4 or
  &value=5 or &value=6 %then %put Value found within list.;
  %else %put Value not in list.;
%mend;
%test(3)

 

OUTPUT:

43   options minoperator mlogic;;
44   %macro test(value)/mindelimiter=',';     By default： mindelimiter = “space”;
45
46   %if &value in 1,2,3,4,5,6 %then
47     %put Value found within list.;
48   %else %put Value not in list.;
49
50   %mend;
51
52   %test(3)
MLOGIC(TEST):  Beginning execution.
MLOGIC(TEST):  Parameter VALUE has value 3
MLOGIC(TEST):  %IF condition &value in 1,2,3,4,5,6 is TRUE
MLOGIC(TEST):  %PUT Value found within list.
Value found within list.
MLOGIC(TEST):  Ending execution.
