Works as being expected for me on SAS 9.2, Winxp 64bit.
65 data one;
66 string = ',leading, trailing,and multiple,,delimiters,,';
67 length word $20;
68 do until(word='');
69 count+1;
70 word=scan(string, count, ',', 'm');
71 output;
72 end;
73 run;
NOTE: The data set WORK.ONE has 1 observations and 3 variables.
NOTE: DATA statement used (Total process time):
real time 0.00 seconds
cpu time 0.00 seconds
Although after you stressed 'm' modifier, you only get one missing 'word'.

Looks like you are running an older version of SAS where SCAN function does not support the modifiers.
