What is this SAS EG Error

Question

I am trying to run some SAS program to query a Oracle DB on SAS EG 9.3. The moment I run the code, I get this red underline and number 49. It doesn't even say "Error" to suspect some syntax errors. Below is a screenshot. Can anyone please help me resolve this issue.

A few lines of the code which gives this error:

%macro pre_network_roll(start);
%let start=%sysfunc(inputn(&start,anydtdte9.));
%let date=%sysfunc(putn(%sysfunc(intnx(month,&start,0,e)),date9.));
