Hi!   I'm using SAS 9.2 and I'm curious about a particular message in the log when accessing a particular dataset through data step.   When the data step is run, the log gives the following warning message   Data Step: data aa; set input.dataset; run;     Message: "WARNING: Integrity constraints cannot be processed for file INPUT.DATASET because its encoding does not match the session encoding or the file is in a format native to another host, such as HP_UX_64, RS_6000_AIX_64, SOLARIS_64, HP_IA64."   However, when I access the dataset through PROC SQL, it gave no such message.   PROC SQL: proc sql; create table bb as select * from input.dataset; quit;     As such, what is the message trying to say? And more importantly, when coming across such a message, is it okay to ignore it and use PROC SQL instead?     Many thanks. Ching Wee ... View more
