When I use two numeric variables to create a third variable, I get a warning in the log saying that "Numeric values have been converted to character values at the places given by: (Line):(Column). 4106:28 4107:10" I have used the code below: if travel_time<=30 then acs=1; /*accessible*/ else acs=0; /*not accessible*/; When I check my proc contents for "acs" variable created above, it shows that the type is Char (len=29), while travel_time is of numeric type (len=8). Can you guy suggest any solution to this? Why am I having this error? Shouldn't I have numeric value for acs when travel_time is all numeric?
