how to use compare function in a macro

[deleted_user]

Hi Guys!
My first post here. So please tell me if there are any rules/principles to follow while posting in this community.

I want to compare a string (which comes from user) to a fixed string inside a macro.
I wanted to use SAS function "compare" but it gives me error.

Here is the relevant code and log

code (from where user call the macro):

%include "E:\Excel Conversion Project\variable analysis\VarAnalysis.sas";
%let SpecialValues= -1, -2, -3, 1, 2 ,3, 9998, 9999, 9000, 9001, 9002, 9003, 8400, 8401, 8402, 8403, 9399, 9398, -599, -598, -597;

ods csv file= "E:\Excel Conversion Project\variable analysis\GD_exampledata_vantage.csv";
%varAnalysis(data1.exampledata, BG90, 1, 10, 1, 1, vantage);
ods csv close;

code (macro):
%macro varAnalysis(InputDataset, DependentVar, Weights, NumOfBuckets, IsNegative, RemoveSpecialValues, PredictorVar);

%if compare(&PredictorVar,allvars, 'i') = 0 %then
%getGraphDataAllVar(&InputDataset, &DependentVar, &Weights, &NumOfBuckets, &IsNegative, &RemoveSpecialValues);
%else
%getGraphData(&InputDataset, &DependentVar, &Weights, &NumOfBuckets, &IsNegative, &RemoveSpecialValues, &PredictorVar);

%mend varAnalysis;

PS: In case I use %if &PredictorVar = allvars %then
the code runs fine. I wanted to use compare function to ignore case, extra spaces etc. Message was edited by: grvs

%sysfunc(compare(&PredictorVar,&allvars,i))
