If you go that way then every proc or datastep you write from that point on will have to be duplicated for each dataset. Unless its for an export of data or report, its never a good idea to split data up - SAS is geared towards using what is called by groups (which...
descriptor information is information about each SAS data set, including data set attributes and variable attributes. SAS creates and maintains the descriptor information. * * Overview of Data Step During the Execution Phase All executable statements in the DATA step are executed once for each iterati...
