Just wondering if there's a single function that will tell me whether a string contains only a specific characater. For example, if I have strings that are number codes of different lengths (e.g., "22313", "4525234", "33232") how can I flag ones that only contain "3"s in them (so yes to "3", "33", "333" and so on but no to "313", "3333313", "3338")?
To check does a numric variable contains only "3"s you may try:
if compress(var,'3') ne '' then ok; else not_ok;
try the function index Character Functions
To check does a numric variable contains only "3"s you may try:
if compress(var,'3') ne '' then ok; else not_ok;
data have; x="22313";output; x="4525234";output; x="33333";output; run; data want; set have; if verify(strip(x),'3') then flag='no '; else flag='yes'; run;
