It will, it will! As the original poster finally mentioned, his dataset
SEARCH contained a variable named NOBS. All of the replies assumed he was
attempting to use the NOBS= option of a SET statement. Since setting past
the end of a dataset stops a data step, when you use the NOBS= option, you
read the variable BEFORE you define it. In the example below, move lines
546 and 547 before line 544 (before the SET statement which will end the
step).
