The paper will start with a simple list input, similar to most examples you see in SAS documents. From there, it will move on to the more typical flat file input. Here we will look first at INFORMATS when reading data, with particular emphasis on DATE variables. After examining INFORMATS, we will look at positioning within our input line. When you omit the MISSOVER option or use FLOWOVER, SAS moves the input pointer to line 2 and reads values for TEMP4 and TEMP5. The next time the DATA step executes, SAS reads a new line which, in this case, is line 3. This message appears in the SAS log. Keyboard Shortcuts:? Show / hide this help menu: Ã—.

Now _INFILE_ is an Automatic Variable − So What? Howard Schreier, U.S. Department of Commerce, Washington, DC ABSTRACT Here’s In earlier versions of SAS® software, _INFILE_ could only be used in the context of the PUT statement.
