The following SAS keywords are recognized even if you don’t spell them correctly:
DATA = dat, dta, daa, ddata, date*
RUN = ru, rn, rnu, urn, ruin, runt*
PROC = pro, prc, poc, porc, pric
QUIT = qut, qui, quti, qit, quite, quiet
SET = sett, sent*
FILE = fil, fill*
OUTPUT = outputsomething, outputnothing*
IF = fi*
THEN = the*
DO = doo*
PUT = putit, putting*
INPUT = imput
END = endit*
This behaviour can be controlled using OPTIONS AUTOCORRECT from SAS 9.3 onwards. To maintain this behaviour use OPTIONS AUTOCORRECT to show warnings in the log, but allow the program to continue, which is the default. OPTIONS NOAUTOCORRECT will show an error in the log at the first incorrect spelling, and then stop the program.
Can you add to my list?
