This may be a bit esoteric, but I was amused that the following can happen:
160 data x;
161 char="Alfred";
162 length num 8;
163 num=substr(char,1,1);
164 run;
NOTE: Character values have been converted to numeric values at the places
given by:
(Line):(Column).
163:7
NOTE: The data set WORK.X has 1 observations and 2 variables.
To my mind, I can't imagine a case where you would want to assign a value
to a numeric variable by substringing an alpha variable, but SAS proceeds
happily along if, before this step, you have coded "missing A;"
Kind Regards,
